- Abstract
- Results are presented for simulation of unconfined round impinging jets at noz-zle-plate distance H/D=2 (D is the nozzle exit diameter) and three Reynolds numbers Re=5000, 23,000 and 70,000 with a k-omega based hybrid RANS/LES (Reynolds-averaged Navier-Stokes/Large Eddy Simulation), dynamic Smagorinsky LES and a RANS k-omega model. With the hybrid RANS/LES model, improved heat transfer results are obtained, when compared to RANS, in the impingement zone and in the developing wall-jet re-gion. For accurate predictions, it is necessary to sufficiently resolve the formation and development of the near-wall vortices in the developing wall jet region.
