Abstract
This presentation discusses the use of Manufactured Solutions for Code Verification of Reynolds-Averaged Navier Stokes (RANS) solvers. In this exercise we will focus on time-averaged (statistically steady), incompressible flows.
Recently, we have developed several Manufactured Solutions (MS) that mimic a near-wall turbulent flow. The proposed analytical functions cover the mean flow quantities and the dependent variables of several eddy-viscosity turbulence models. Namely, the undamped eddy-viscosity of the Spalart & Allmaras and Menter one-equations models, k1/2L from the one (SKL) and two-equation (KSKL) models proposed by Menter, the turbulence kinetic energy and the turbulence frequency included in two-equation k-w models. The turbulence quantities are defined from “automatic wall functions” and so they are supposed to reproduce the expected behaviour of these variables. All flow fields satisfy mass conservation, i.e. mean velocity fields are divergence free.
