Aerodynamic field around dry cooling tower is presented with numerical model. Performances of cooling deltas are figured out by air inflow velocity analysis. Setting angles of wind-break walls are optimized to improve cooling performance. Optimized walls can reduce the interference on air inflow at low wind speeds. Optimized walls create stronger outside secondary flow at high wind speeds.
