Abstract
AbstractThis study summarizes the scaling behavior of single laminar submerged jets with circular and planar cross sections. Unified correlations for the stagnation zone heat transfer of both configurations, based on the dominant dimensionless numbers, are presented. In technical applications, impinging jets are often applied in jet array configurations. Compared to single jet impingement, jet‐to‐jet interaction can have a substantial influence on local heat transfer. A distinct pattern of the heat transfer coefficient was observed experimentally. Numerical simulations revealed two counter‐rotating vortices in the interaction zone between two jets to be the causing mechanism of this pattern. (© 2016 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
