Verification and Validation of Adaptive Finite Element Method for Impingement Heat Transfer

Abstract

Aadaptive finite element computations of laminar and turbulent jet impingement heat transfer are presented. Turbulence is modeled using the standard κ-e model for high Reynolds number, coupled with wall functions. The turbulence model is solved in logarithmic form. The error estimator uses a local least-squares projection of derivatives and accounts for errors in all dependent variables, including the eddy viscosity. The performance of the methodology is verified by solving a problem possessing a closed-form solution. Two applications are then considered: laminar and turbulent impinging jets. In both cases heat transfer is a key element of the study
