Interfaces in soft materials often exhibit deviation from non-slip/stick response and play a determining role in the rheological response of the overall system. We discuss detection techniques for the excess interface rheology using small-amplitude o

The mixing characteristics of a Dulmage-type screw, a kind of distributive mixing element, in single-screw extrusion were investigated. To evaluate the mixing ability, a melt-mixing extrusion experiment diluting a masterbatch with its base polymer an

We have released a colloid simulator named KAPSEL implemented the “Smoothed Profile (SP) method” which has been developed by ourselves for direct numerical simulations of particulate flow providing a way to couple continuum fluid dynamics with ri

A general method is presented for computing the motions of hydrodynamically interacting particles in various kinds of host fluids for arbitrary Reynolds numbers. The method follows the standard procedure for performing direct numerical simulations (D

A novel simulation technique for the flow in plastic mixers based on Element-free Galerkin Method (EFGM) has been developed in this study. To improve the simulation accuracy, a “rearrangement” scheme has been employed which eliminates errors caus

To elucidate the key factor for the quantitative prediction of the shear-thickening in suspensions in viscoelastic fluids, direct numerical simulations of many-particle suspensions in a multi-mode Oldroyd-B fluid are performed using the smoothed prof

Mathematically, the problem of flow field classification can be analyzed by the eigenanalysis of the deformation-rate tensor; however, such analysis technique have not been commonly applied in fluid processing. We derive a simplified objective flow c

We investigate previously unclarified effects of fluid elasticity on shear-thickening in dilute suspensions in an Oldroyd-B viscoelastic fluid using a novel direct numerical simulation based on the smoothed profile method. Fluid elasticity is determi
