Abstract: Flow fields were simulated by mathematical software between two corrugated plates in chevrontype plate heat exchanger. Simulation results confirm the changing rule of fluid's flow pattern between corrugated plates affected by corrugation inclination angel β reported by correlated literature, namely the flow pattern in channel between two plates changed from ‘crossflow’ to ‘zigzag flow’ with angel β increasing. The simulation results show that corrugation inclination angel β is not the only factor affects the flow pattern in chevrontype plate heat exchanger, but the others geometric parameters of corrugation can also affect the flow pattern. From the view of coactions of both component of flow momentum and flow resistance in direction of corrugations, the essential mechanism of the flow pattern in channel between two chevrontype corrugation plates affected by corrugation geometric parameters was discussed.

Key words: simulation, flow pattern, flow field , plate heat exchanger
