Cellular Automaton Simulation for Convective Mass Transfer in Channel with Rough Surface.

The convective mass transfer in a channel with the rough surface is investigated by the use of the cellular automaton method. The Greatz problem is simulated by the cellular automaton method. It is shown that the simulation result is consistent with the analytical solution. The cellular automaton method is applied to the mass transfer problem in the channel flow with the rough surface. The local Sherwood number and bulk mean concentration are calculated. It is shown that the mass transfer rate increases with the size of roughness.
