This paper addresses the method of manufactured solutions for RANS solvers, i.e. in the context of the calculation of incompressible turbulent flows with eddy-viscosity turbulence models. The difficulties caused by damping and/or blending functions included in the turbulence models are discussed. The need to manufacture the turbulence quantities...

This paper presents an exercise of Code Verification with two manufactured solutions valid for 2D RANS equations supplemented either with the one-equation Spalart & Allmaras or with the two-equation BSL k-w turbulence model. When the manufactured solution is applied with the eddy viscosity frozen, second order convergence behaviour is shown....

This paper discusses the abilities of two different low-Reynolds-number eddy-viscosity models in resolving the complex physical features that arises in turbulent flows around a square cylinder at Re=22000. For the modeling of turbulence, the Launder & Sharma (LS) [1] and Kawamura & Kawashima (KK) [2] low-Re models have been employed. The present...
