Numerical assessment of different turbulence models for slot jet impinging on flat and concave surfaces

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for C<sub>μ</sub> was also introduced to account for the better prediction of the wall jet development. The studied Reynolds numbers vary from 8,000 to 20,000, and nozzle-to-surface distance (H) is in the range of 1 [less-than or equal to] H/B [less-than or equal to] 8. Detailed comparison is made between the results from the models and available experimental data to test the ability of the models in predicting these fluid flow and heat transfer problems.
