Computational Fluid Dynamics facilitates in the quantitative analysis of haemodynamic processes of in vivo cardiovascular systems. The objective of the present study is to examine the effects of different branching angles of diseased renal arteries with respect to the abdominal aorta on its flow characteristics. Secondly, simulation of normal renal arteries at similar branching angles were also done as a baseline for comparison to comprehend if geometry played a role in the endothelial proliferation in renal artery stenosis. Idealistic renal artery models generated from the digital image of computerized tomography scan were used, with bifurcation angles at the junction ranging from 30° to 90° at successive intervals of 15°. Virtual stenosis of a degree below and above 80% by diameter were generated on the right and left renal artery respectively. The models were discretized using a hybrid polyhedral mesh. Parameters such as time-averaged velocity, time-averaged wall shear stress, pressure difference and fractional flow reserve were used to analyse the flow characteristics. Stenosed renal arteries with higher angulation was found to have larger flow recirculation zones, higher pressure gradient near the Ostia and was observed to experience greater amounts of shear stress at the region of stenosis. For the same degree of stenosis (above 80%), the blockage tended to increase from 18% to 25%, as the angle increased. The effect of angulation was observed to alter the flow characteristics significantly in the stenosed arteries. Critically stenosed (above 80%) renal arteries at a bifurcation angle above 45° showed signs of ischemia.

Fluid-Structure Interaction in Problems of Patient Specific Transcatheter Aortic Valve Implantation with and Without Paravalvular Leakage Complication Reviewed International journal

Basri A.A., Zuber M., Basri E.I., Zakaria M.S., Aziz A.F.A., Tamagawa M., Ahmad K.A.

Fluid Dynamics and Materials Processing 17 ( 3 ) 531 - 553 2021.01

Language：English Publishing type：Research paper (scientific journal)

Paravalvular Leakage (PVL) has been recognized as one of the most dangerous complications in relation to Transcathether Aortic Valve Implantation (TAVI) activities. However, data available in the literature about Fluid Structure Interaction (FSI) for this specific problem are relatively limited. In the present study, the fluid and structure responses of the hemodynamics along the patient aorta model and the aortic wall deformation are studied with the aid of numerical simulation taking into account PVL and 100% TAVI valve opening. In particular, the aorta without valve (AWoV) is assumed as the normal condition, whereas an aorta with TAVI 26 mm for 100% Geometrical Orifice Area (GOA) is considered as the patient aorta with PVL complication. A 3D patient-specific aorta model is elaborated using the MIMICS software. Implantation of the identical TAVI valve of Edward SAPIEN XT 26 (Edwards Lifes ciences, Irvine, California) is considered. An undersized 26 mm TAVI valve with 100% valve opening is selected to mimic the presence of PVL at the aortic annulus. The present research indicates that the existence of PVL can increase the blood velocity, pressure drop and WSS in comparison to normal conditions, thereby paving the way to the development of recirculation flow, thrombus formation, aorta wall collapse, aortic rupture and damage of endothelium.

In order to investigate various dangers of fall down, we have conducted the experiment using human dummy model in Japan Automobile Research Institute (JARI). We have measured accelerations inside of the head in time step of 1/10000 sec with the accuracy within 1%. From the acceleration, we calculate the time development of velocity and position of the center of the head. HIC and the deformation are calculated. for two backward falls from standing position. As a conclusion, we found the deformation of the skull is similar, about 2.4mm for two falls down, although their HIC are different from each other .

MIYAMURA Yuko, SHET Pramod, YOSHIMUTA Junichiro, PAI Raghuvir, TAMAGAWA Masaaki

Proceedings of the Annual Conference of Biomedical Fuzzy Systems Association ( Biomedical Fuzzy Systems Association ) 30 ( 0 ) 161 - 164 2017.11

Authorship：Corresponding author Language：Japanese Publishing type：Research paper (conference, symposium, etc.)

This paper describes the relation between infantile crying and thrombus generation near intravenous indwelling needle in veins. In this study, it is assumed that the difference of pressure or flow rate between normal and infantile crying causes thrombus formation. First of all, the blood pressure of infant are measured, and the difference of blood pressure between normal status and infantile crying. It was found that the blood pressure increases according to the infantile crying, and the difference of blood is approximately 20 mmHg. To investigate the flow field of the flow, CFD analysis around the indwelling needle of drip injection (catheter) in the infantile vein was done. The results show that the increasing flow rate or velocity make the accumulation of particle around the inlet of the catheter.

A new method of wastewater treatment using electric discharge in the water cavitation field formed by a large number of micro bubbles generated by high-speed water flow is proposed in this paper. Indigo carmine solution, which is a type of dye, with a concentration of 9 mg/liter was used as the specimen solution for demonstration of water treatment. The total volume of solution and the average speed of solution in the cavitation field were 20 liters and about 7.4 m/s, respectively. An absorbance decrease rate of 96% was obtained in 50 min of treatment time at the electrode distance of 2 mm and discharge power of 16 W. It was also found that the efficiency of decolorization was improved by changing the electrode location. © 2013 Wiley Periodicals, Inc.

This paper describes the development of ballast water treatment systems using interaction of bubbles, shock waves and discharges. In this development, we have cavitation flows during nozzle and diffuser part (reactor) and discharge in this cavitation area. The aim of this investigation is to satisfy the IMO standard for ballast water treatment by using our special cavitation discharge water treatment system, and to modify the geometry of reactor part in the circuit by using simple measurement method of the bubble density and diameter. In this paper, it is concluded that (1) the disintegration rate of plankton (more than 50 μm) by using cavitation discharge is satisfied in IMO standard (D-2), (2) by simple measurement method, the result of bubble density distribution in the reactor almost agrees with the position of electro node for discharge optimized with efficiency in the previous experiment. © 2012 The Japan Society of Mechanical Engineers.

This paper describes the prediction of index of thrombus formation in shear blood flow by computational fluid dynamics (CFD) with Lattice Boltzmann Method (LBM), applying to backward facing flow, which is simple model of shear flow in the rotary blood pumps and complicated geometry of medical fluid devices. Assuming that the blood flow is multiphase flow composed of blood plasma and solid protein, the effects of surface tension and adhesion force to the wall are added to LBM computation. It is found that the thrombus formation occurs just after the reattachment point and behind the step. These results correspond to our previous observation results. To predict thrombus formation in every case of blood flow, effects of threshold level of physical parameters such as shear rate, adhesion force (effective distance from the wall) are estimated.

This paper describes prototype of microcapsule including a bubble for Shock Wave Drug Delivery Systems and evaluation of their mechanical properties. Microcapsules are generated by dropping mixed solution of Sodium Alginate and Polyvinyl Alcohol (PVA) into Calcium Chloride solution (CaCl2) Young's modulus are estimated by an aspiration experiment and its numerical analysis. Liquid and gas are injected into the microcapsules on micromanipulation system by hand. The result showed that microcapsules generated by low concentration of Sodium Alginate, PVA, and CaCl2 are able to be injected by micropipette and to make the microcapsule including a bubble. Furthermore, we found the existence of threshold value of apparent Young's modulus between able or disable of injection on the assumption of visco elasticity of microcapsule shell.

This paper describes a numerical prediction method for hemolysis properties in orifice-pipe blood flows. In this study, several types of orifice-pipe flows by using two turbulence models are computed, which are ( 1 ) standard low Reynolds number k-ε model and (2 ) the k-ε model with partly patched Launder-Kato model (LK-Zonal model) to improve computational accuracy. These predicted flows are compared with (a) measuring pressure loss and (b) measuring reattachment length, and it is found that the flow using LK-Zonal model has good agreement with experiments. Then the hemolysis properties are estimated from the predicted flows. The results are 1) computational accuracy of orifice-pipe flow is improved by using LK-Zonal model, 2) accuracy of predicted hemolysis is also improved especially in orifice-pipe that have long contracted part.

This paper describes the particle inertia and the contact with the wall of red blood cells on the variance of particle path, that should depend on the hemolysis properties. The new methods of examining the inertia of red blood cells (particle) on particle path are discussed using computational fluid dynamics (CFD). In this method, the particles are moved by Stokes drag including effects of difference between density of plasma and internal liquid in the blood. The results of analysis by this method show that (1) the diameter of the particle (red blood cell) that means inertia of the cells, (2) the configuration of the objective wall boundary are important factor. These results also show that if the inertia and the contact with the wall are considered, the precision of the prediction of the hemolysis properties will be progressed.

This paper describes a method of predicting hemolysis induced by turbulent shear stress (Reynolds stress) in simplified orifice pipe flow. In a centrifugal blood pump, serious hemolysis occurs at the impeller or the casing edge. The turbulent shear stress computed using a low-Reynolds number k-ε model near the edge proves to be several hundred times the laminar shear stress (molecular shear stress). The peak turbulent shear stress is about 2 500 Pa, which is much larger than that obtained from a conventional hemolysis test using viscometer. Then the threshold of turbulent shear stress for hemolysis is determined by comparing with that obtained in hemolysis experiments of pipe-orifice blood flow.
