摘要:
Extensive study of micro flow in rectangular channel is considered and analyzed. Numerical studies are performed by Lattice Boltzmann Method. A new combination bounce back model for the treatment of solid boundary condition is proposed. Then, three solid boundary conditions are implemented in micro rectangular channel flow. These include non-slip bounce back rule, traditional combination bounce back rule and the proposed combination bounce back rule. It is observed that the width-to-height ratio ...More
