Using numerical methodology, the flow fields between two corrugated plates with different values of the corrugation inclination angle β were simulated.The simulation results directly indicate that β affects the flow pattern between corrugated plates, and the results are in good agreement with the experimental results reported by interrelated literature.The results show that the flow pattern between the two plates changes from "double cross-flow" to "zigzag flow" with the increase in β.The reason for the effect on the flow pattern between the two corrugated plates was discussed from the view of the variation of momentum in the direction of corrugation with the variation in β.
