- KAPSEL is a software designed specially to simulate the dynamics of solid particles dispersed in simple and complex fluids using SPM (Smoothed Particle Method). KAPSEL is a stand-alone simulator but also works as an add-on engine of OCTA.
- SPM is an unique simulation method which enables us to perform direct numerical simulations (DNS) for several particulate fluids and colloidal dispersions. To compute the correct time evolutions of the dispersed particles
and the host fluid simultaneously, SPM provides an extremely efficient numerical scheme to solves the following coupled equations.
- Newton's and Euler's equations of motion (translational and rotational motions of the dispersed particles)
- Navier-Stokes equation (fluid flow)
- advection-diffusion equation (densities of counter- and co-ions in cases of electrolyte solution)
- One can thus perform reliable simulations for particulate systems in which the hydrodynamic interactions (sedimentation, coagulation, rheology, etc) and the electro- hydrodynamic couplings (electrophoresis, electro-osmosis, etc) are important. See this paper for details of SPM.
