Abstract:
Objective To verify the flow field performance of the air dynamic wind tunnel. Methods The performance of the flow field was evaluated by testing the flow speed of sample-point on the sample-transect of the tunnel. Results Among the flow range of the tunnel, the relative deviations of the speeds of each sample-point on the sample-transect were less than 10%. When the flow rate was set, the relative deviations of the sample-transect average speed in different test period were less than 10%. The ratio of average wind velocity of upper reach to down reach of the tunnel was between 0.92 and 1.03. Conclusion The flow field of the air dynamic wind tunnel is even, stable and coincident.
