Application of quadratic constitutive relation to one-equation k-kl turbulence model

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

This paper analyzes the accuracy of the recently developed one-equation k-kL turbulence model with Quadratic Constitutive Relation (QCR) compared to the linear Boussinesq relation. The computational results for several benchmark cases from NASA TMR are compared to the results from other widely used one-equation turbulence models, such as Spalart-Allmaras model (SA) and Wray-Agarwal model (WA). In particular, one-equation k-kL-QCR model shows good agreement with experimental and DNS data, especially for supersonic flow in a square duct where the effect of QCR is clearly visible in capturing the secondary flow vortices which is not feasible with the any standard model without QCR. In several other test cases, k-kL-QCR model improves the results predicted by k-kL model.
