Summary: | 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.
