APPLICATION OF LATTICE BOLTZMANN METHOD AND FIELD SYNERGY PRINCIPLE TO THE HEAT TRANSFER ANALYSIS OF CHANNEL FLOW WITH OBSTACLES INSIDE

ABSTRACT
In this paper the lattice Boltzmann method and field synergy principle are applied to simulate two-dimensional incompressible steady channel flow under low Reynolds number, and analyze the local influence on velocity field and temperature field caused by inserting cylinder obstacles of different cross-section. Furthermore, field synergy principle of elliptic flow type is applied to demonstrate that the increased interruption within the fluid increases the synergistic level between the velocity field and temperature gradient field. As the intersection angle between the velocity vector and the temperature gradient vector decreases by inserting cylinder obstacles to fluid field, the results of heat transfer will improve significantly.
