Summary

Uniform air flow distribution is an important and fundamental issue to miscellaneous equipments. The detailed design method and design principle are presented in this work. The practical application for uniform air flow distribution is conducted according to the employed design method. Finite volume method (FVM) is used to verify the designed validation. The numerical treatment of convection terms in governing equations is based on the quadratic upwind interpolation of convective kinematics (QUICK) scheme. The well-know semi-implicit pressure-linked equation (SIMPLE) algorithm is used to treat the coupling of pressure and velocity fields. It is found that the design method is validated for the uniform air flow distribution. The unbalance rate of air flow distribution is less than 10%. Moreover, the uniform of air flow distribution can be further improved by adding vertical baffles. The developed design method is of great significance to obtain uniform air flow distribution.
