SIMULATION OF FLOW FIELD AND PERFORMANCE ANALYSIS OF CROSS-FLOW FAN

Abstract

Abstract: The internal flow of a cross-flow fan is simulated with CFD software STAR-CD, and the influence of structure parameters on the performance of the cross-flow fan is analyzed. The structure parameters include volute tongue clearance, inlet angle, volute case clearance, volute tongue angle, outlet angle and so on. Based on the analysis of the influences of the structure parameters on the velocity of inlet and outlet, the relationship between the structure parameters and the flow filed of the cross-flow fan can be determined. Some calculated results are verified by the experimental data and show they are reasonable.

Key words: CFD, Cross-flow fan, Numerical simulation, Structure parameters
