© 2015 The Authors.In this study, the fluidization characteristics for fine cohesive powders under mechanical vibrating conditions were experimentally investigated. In a case of handling of fine cohesive powders with fluidized bed, stable gas channels and cracks were easily formed in the bed due to the strong cohesiveness acting among particles. A mechanical vibration is one of the methods to improve the fluidity of fine cohesive powders. In this study, we focused on the transition of the dominant bed flow pattern induced by mechanical bed vibrating conditions. The powders used in this study were different sizes (0.7 - 20 μm) and materials (silica, alumina, polymer). All powders belonged to group-C in the Geldart classification. The bed expansion ratio was lower in the relatively smaller vibration strengths regardless of the gas velocity, however, it steeply increased with larger a certain vibration strength. Form the visual observation of the bed, the bubble formation appeared with larger than such a critical vibration strength. This implied that the dominant bed fluidization pattern was transitioned from channeling behavior (group-C) to bubbling behavior (group-A or -AC) by the addition of the mechanical vibration.

Mathematical derivation of a coating drying model using the Maxwell-Stefan equation 査読有り

記述言語：英語掲載種別：研究論文（学術雑誌）

In contrast with the Generalized Fick (GF) equation and estimated Fick diffusion coefficient hitherto employed in mathematical modeling of coating drying, in this study a set of basic equations was derived based on the Generalized Maxwell-Stefan (GMS) equation and use of measured mutual diffusion coefficient, and the drying processes of binary and ternary components system were considered. Restrictions of wet coating on base film without penetration were considered through the derivation as follows: volumetric flux of mass transfer is always zero on the bottom of the coating, and the coating shrinks during drying. © 2013 The Society of Chemical Engineers, Japan.

Film thin drying is a process to create functional interfaces in solidifying liquids, rather than to separate volatile components from solutions or suspensions. Indeed, recent developments in coating technologies have shed light on self-organization in evaporating complex thin fluids. In particulate coatings, final properties of dried film depend not only on initial liquid compositions but also the imposed drying conditions, which significantly influence local particle distributions, contact area of rigid and/or deformable particles, anisotropic particle orientation, and amounts of adsorbed molecules on particle surfaces. It is of importance to understand how a directional film shrinkage and spontaneous solidification constrain the particle motions, and how they induce particular film structures in a non-equilibrium state. Recently, there has been a great deal of progress in measurement techniques and numerical approaches for analyzing transient structures in evaporating thin liquid films. This article presents an overview of current research activities on local, in-situ determination of (i) fluid properties at air-liquid and liquid-liquid interfaces, and (ii) distributions of particles or solutes in the thickness direction in shrinking films. © 2011 Hosokawa Powder Technology Foundation.
