The behavior of supercooled polymer melt composed of short chains with 10 beads between rapidly oscillating plates is simulated by using a hybrid simulation of molecular dynamics and computational fluid dynamics. The flow profiles of polymer melt ...
We develop a method for multiscale hybrid simulations of molecular dynamics (MD) and computational fluid dynamics (CFD). In this method, the usual lattice-mesh based simulations are applied for the CFD level, but each lattice is associated with a ...

The steady-state simplified P-N approximation to the radiative transport equation has been successfully applied to many problems involving radiation. This paper presents the derivation of time-dependent simplified P-N (SPN) equations (up to N = 3)...

The half-space problem of the temperature, pressure, and concentration jumps for a binary mixture of vapors is investigated on the basis of the linearized Boltzmann equation for hard-sphere molecules with the complete condensation condition. First...
A kinetic transport equation for chemotactic bacteria, i.e., a kinetic chemotaxis equation, coupled with reaction-diffusion equations for chemoattractants is considered. The Keller-Segel type equation for the population density of bacteria is deri...
