3-d numerical investigation of flow field in starting stage of high speed wind tunnels

چکیده
high speed wind tunnels are widely used in the study of fluid flow behavior around various objects. the air flow in the starting step of supersonic wind tunnels is transient including strong shock waves caused by the interaction of the tunnel main stream and the boundary layer at walls. to arrive in running step, the tunnel must be designed so as these waves leave immediately the test section. otherwise, they will hinder the air flow through the tunnel. accordingly, as a clear practical fact, the tunnels unable to pass the starting step are considered as unusable.in this paper, a 3-d computational fluid dynamic analysis of the starting stage of a supersonic wind tunnel with a target mach number of 3 is performed. the results obtained in this work are in agreement with the expected physical behavior of the flow field and can be applied as the designcriterion of the high speed wind tunnels.

متن کاملFlow Visualization in Wind Tunnels
Flow visualization is an experimental means of examining the flow patterns around a body or over its surface. The flow is “visualized” by introducing dye, smoke or pigment into the flow in the area under investigation. The primary advantage of such a method is its ability to provide a description of the flow over a model without a complicated data reduction and analysis. Smokeflow visualization...
