title = "Turbulence modeling of high speed compressible flows",
abstract = "It is well known that the two-equation turbulence models were originally developed and applied to compute flows in subsonic and transonic regimes at relatively low Mach numbers. This paper employs a new temperature gradient correction to the eddy viscosity term in a two-equation k-ε turbulence model for computing flows at high Mach numbers. The accuracy of the improved k-ε model is assessed by computing the supersonic/hypersonic boundary layer flow over a flat plate and the jet flows from supersonic nozzles. The results of computations using the modified k-ε model are in better agreement with the available theoretical and numerical results, and experimental data compared to those obtained with the industry standard two-equation k-ε and SST k-ω models.",
