This study applies the lattice Boltzmann method (LBM) to simulate incompressible steady low Reynolds number backward-facing step flows. In order to restrict the simulations to two-dimensional flows, the investigated Reynolds number range is limited to a maximum value of Re=200. The field synergy principle is applied to demonstrate that the increased interruption within the fluid caused by the introduction of two inclined plates reduces the intersection angle between the velocity vector and the temperature gradient. The present results obtained for the velocity and temperature fields are found to be in good agreement with the published experimental and numerical results. Furthermore, the numerical results confirm the relationship between the velocity and temperature gradient predicted by the field synergy principle.

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.
