Empirical and numerical studies on gas entrainment by impinging jets

This work concerns experiments as well as CFD simulations on the gas entrainment for the impinging jet configuration. Impinging jets may occur in different situations related to reactor safety analyses. Many experiments have been carried out on impinging jets. A comprehensive overview by Bin [1993] reveals that the results depend critically on the individual setup (e.g. the nozzle geometry) and it is difficult to draw general conclusions. For the qualification of Computational Fluid Dynamics (CFD) models for such flow situations data with high resolution in space and time are required. Therefore a new experiment with a very simple setup was designed and first CFD simulations were done for these experiments.
