Abstract
We study a thermal boundary condition which is robust and applicable to a wall along which temperature varies. A framework to derive robust thermal boundary conditions using the Maxwell-Boltzmann statistics is proposed for the purpose of the thermal boundary condition of the discrete kinetic theory. The thermal exchange between fluid particles and walls is achieved by using the relation between the velocity change rate and temperature so that we can control the velocity change rate according to a given temperature boundary condition. We simulated microchannel flows by the lattice gas cellular automata and the direct simulation of Monte Carlo.
