Abstract

Experimental and computational studies on supersonic mixing by the slotted injection with various injection angle have been conducted. In the experiment flat plate model is installed into supersonic free stream of Mach number of 4 and fully developed turbulent boundary layer is established on the flat plate. The secondary jet is injected through slot nozzle set on the flat plate model in order to simulate supersonic mixer. Experiments are conducted by changing injection angle of helium gas in order to observe the effect of injection angle to super sonic mixing. The flow fields are visualized by the Schulieren method. Also surface pressure distributions and spatial distributions are measured. The same flow fields are simulated by solving two-dimensional full Navier-Stokes equation of two components of mixture gas and calculated results are compared with experiments. Quite good agreement is obtained between experimental result and numerical result. By using the calculated results, the correlation between mixing rate and total pressure loss of the flow field is obtained.
