Monolithic Approach for Fluid-Structure Interaction Based on Consistent Pressure Poisson Equation Reviewed

ISHIHARA Daisuke, YOSHIMURA Shinobu

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B ( The Japan Society of Mechanical Engineers ) 71 ( 706 ) 1565 - 1572 2005.06

This paper describes a new monolithic approach based on the Pressure Poisson Equation (PPE) to solve interaction problems of incompressible viscous fluid and an elastic body. The PPE is derived so as to be consistent with the coupled equation system for the fluid-structure interaction (FSI). Based on this approach, we develop two efficient monolithic methods. In both methods, the fluid pressure is derived implicitly so as to satisfy the incompressibility constraint and all the other unknown variables are derived fully explicitly or partially explicitly. The coefficient matrix of the PPE for the FSI has characteristics of (a) symmetric and positive definite feature, (b) reduction of degrees of freedoms to be solved, and (c) less dependence of the condition on material properties. The arbitrary Lagrangian Eulerian method is employed for the fluid to take into account the deformable fluid structure interface. To demonstrate fundamental performances of the proposed approach, the developed two monolithic methods are applied to simulate the vibration of a rectangular cylinder induced by vortex shedding.

This paper describes a strong coupling method considering non-conforming mesh on fluid-structure interface. In the present method, a transformation matrix derived from the geometrical relations between non-conforming fluid and structural meshes on fluid-structure interface is directly combined with the formulation of the strong coupling method to satisfy the compatibility and equilibirium conditions on fluid-structure interface. The conjugate gradient method is applied to solve the derived coupled equation system by introducing the consistent pressure Poisson equation. To verify basic characteristics of the proposed method, it is applied for free vibration of a cylinder in quiescent fluid. The added mass and damping coefficients derived by the present method agree well with those by other researchers.

Efficient Strong Coupling Method for Fluid-Structure Interaction Based on Explicit Method for Structure and Semi-implicit method for Fluid Reviewed

ISHIHARA Daisuke

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B ( The Japan Society of Mechanical Engineers ) 70 ( 700 ) 3098 - 3105 2004.12

Authorship：Lead author Language：English Publishing type：Research paper (scientific journal)

This paper describes an efficient strong coupling method for fluid-structure interaction based on the explicit method for structure and the semi-implicit method for fluid. The solution process of fluid-structure interation system is divided into that of fluid and structure, which is independent to each other except data transfer of the fluid-structure interface. Some existing codes with small modification can be utilized to realize the above two solution processes. Note that the time increment is restricted by the Courant's and diffusive number conditions. The method is applied to solve a loaded cantilever in a flow channel under some conditions. Through the numerical results, characteristics of the method are compared to those of a strong coupling and a weak coupling method

This paper describes a multi-step strong coupling method to analyze an equation system of incompressible viscous fluid and an elastic body. The procedure is derived based on the following techniques; (a) sub-structuring, (b) velocity-pressure splitting, and (c) time integration of Newmark's family. Only simultaneous equations with well-defined symmetric matrices are solved in the method. To demonstrate fundamental performance of the method, it is applied to solve an impacted beam in fluid. The result shows good agreement with a previous work.

This paper proposes an automated search method for multidimensional design window (DW), which is defined as an area of satisfactory design solutions in a design parameter space, using both continuous evolutionary algorithms (CEA) and improved K-means clustering. This method consists of two phases: (a) CEA-based search for satisfactory design solutions in an ill-structured design space, and (b) clustering-based identification of DWs from the solutions. To demonstrate practical performance of the method, it is applied to an automated structural design of micro electrostatic actuator for optical memory. © 2001, The Japan Society of Mechanical Engineers.
