内容記述 | The boundary layer along a wind-tunnel contraction nozzle is investigated in detail using hotwire anemometry and flow visualization method. It is found that Gortler vortex system exists and develops in the concave wall region of the contraction nozzle. In spite of the flow acceleration by the contraction the disturbance enhanced by the Gortler vortex system travels down even to the test section. It was found that this disturbed region at the test section is more than 35 percent of the cross-sectional area. This result shows the effects of the Gortler vortex system should be taken into consideration in designing a wind-tunnel contraction nozzle. When acceleration parameter is large enough to laminarize the boundary layer, the boundary layer at the outlet of the contraction nozzle becomes to be laminar. Acceleration parameter is also important to design contraction nozzle. | |||||
