The aeronautic disturbance of hot wire anemometry should be considered in turbulent flow velocity measurements.The multi position rotating methods with inclined single wire are studied in this paper.In view of the velocity profile characters of the swirl jet and the response of the inclined single wire probe perpendicular to the main flow,the optimized data process is introduced.The experimental results show that the optimized solution is more exact.
