| Research Abstract |
We developed a unique numerical method for direct numerical simulations of dense dispersions of colloidal particles. This method, which we named the smoothed profile (SP) method, enables us to compute the time evolutions of colloidal particles, ions, and host fluids simultaneously by solving Newton-Euler, advection-diffusion, and Navier-Stokes equations so that the electro- hydrodynamic couplings can be fully taken into account. We have applied the SP method successfully for simulating the dynamics of various problems of particle dispersions, including dispersed particles in compressible fluids, 2) dispersions of self-propelled particles (squirmer), and 3) dispersions of non-sperical rigid particles (arbitanary shape by assembling multiple spheres.
