CFD Investigation of Supersonic Free Jet from a CD Nozzle

Conference paper
Part of the Lecture Notes in Mechanical Engineering book series (LNME)


The rate at which supersonic jet mixes with the surrounding ambient fluid includes turbulent mixing and compressibility effects such as isentropic expansion and shock. Numerical simulations are performed using commercially available software FLUENT 12.1 v to investigate supersonic jet flow field mixing with surrounding medium. CFD investigations consider unheated, supersonic free jets on generic CD nozzle operating at M = 1.4, from NASA/TM—2004–212391. Based on the results, 1.5D height of refinement grid in the normal direction shows good agreement with test data such as velocity, density and temperature measurement along jet centre line. Secondly, from turbulence models, it is understood that both SA and KE models with default turbulent settings captured velocity decay and potential core along the centre line and found good agreement with test data.
