On the Numerical Modeling of Impinging Jets Heat Transfer - A Practical Approach
Artikel i vetenskaplig tidskrift, 2013

This article compares steady-state and transient simulations in predicting impinging jet heat transfer. The configurations tested are H/D=2 and 6, Re=10,000, 20,000, 23,000, and 30,000. The variables considered are: turbulence model (LES, k-E, k-, V2F), discretization schemes, mesh density and topology, inlet velocity profile, and turbulence. The V2F model performs best for the steady state simulations. The inlet velocity profile plays an important role. Mesh topology and distribution is also important. The turbulence created in the shear layer plays a stronger role than the inlet turbulence. The LES model reproduces the turbulent structures with a useful degree of accuracy.
