Abstract
The inability of standard Reynolds-averaged Navier-Stokes turbulence models to reliably predict hypersonic shock-boundary layer interactions presents a major obstacle to efficient, engineering level analysis of hypersonic vehicles. Current work at North Carolina State University seeks to develop modifications to these models informed by data mining of experimentally anchored high-fidelity large eddy simulations. In this companion effort, two-equation turbulence modeling capabilities in a prototype version of the COFFE finite element solver are expanded and matured, with the goal of positioning COFFE to rapidly realize any model improvements emerging from the NCSU investigation. To that end, the k -ln(ω) model framework, based on the 1988 Wilcox k - ω turbulence model and designed to improve the compatibility of two-equation turbulence models with finite-element flow solvers, has been extended to include Menter k - ω model variants. The modified Menter models are tested on several benchmark validation cases, including a Mach 7 axisymmetric shock-boundary layer interaction.
