This paper presents a comprehensive study of an impinging jet configuration (Grenson et al, Int J Heat Mass Trans 102:801–815, 2016), which has been selected for its high Reynolds number ReD = 60,000, small nozzle-to-plate distance H/D = 3 and temperature difference between the heated jet and the ambient. First, the experiments are described and analysed, then numerical simulations (DNS, LES, ZDES and RANS) are assessed to evaluate the resolution level required to capture the salient features of this configuration. |
