The results showed that both the f and j factors are increased with the increase of the uniform louver angle; for a given louver pitch, increasing the uniform louver angle(θ_uniform), from 20° to 28°, the f and j factors are increased by 25.7% and 61.1%, respectively. Besides, the numerical results showed that both the f and j factors are also increased with the increase of the successive variable angle; with the same initial louver angle(θ_initial =20°), increasing the successive variable angle(Δθ), from 0° to 3°, the f and j factors are increased by 19.6% and 32.8%.Finally, the results of optimization analysis revealed that, with inlet frontal velocity ranging from 1 to 12 m/s, the optimal values of initial louver angle and successive variable angle are in the range of (18° to 23° ) and (2.5° to 3°), respectively. It is also found that, under the optimum conditions, the area reduction ratio could reach up to 33.3 % to 63.4%.
