A priori tests of eddy viscosity models in square duct flow

We carry out a priori tests of linear and nonlinear eddy viscosity models using direct numerical simulation (DNS) data of square duct flow up to friction Reynolds number Re _τ= 1055. We focus on the ability of eddy viscosity models to reproduce the anisotropic Reynolds stress tensor components a_ij responsible for...

Development of the Generalised Hybrid Turbulence Model for RANS simulations

Turbulence plays an important role in a broad range of engineering applications. In the industry RANS simulations are a common method for predicting turbulent flow. A broad range of RANS turbulence models have been developed over the past decades. For the assessment of complex three-dimensional flow fields Reynolds Stress Transport Models are a...
