　　Turbulent flow-filed characteristics in the 180° curved duct with circle cross-section were investigated.The profiles of tangential velocity and pressure were measured by using five-hole probe and simulated by FLUENT 6.2.The results show that centrifugal force generates as fluid rotating, which is contributed to the change of tangential velocity and pressure.
