Calculation of the end plates frictional resistance effect on the flat jet dynamics

Abstract

This article is a continuation of scientific research on the calculation of the effect of friction resistance of end plates on the aerodynamics of a flat jet. In the previous works, the resistance was calculated for a turbulent boundary layer. This paper shows the results of calculating the effect of friction resistance of end plates on the patterns of development of a flat free jet. A flow diagram of the jet between the end surfaces has been constructed. The resistance calculation for the laminar boundary layer has been carried out. The formula for calculation of the change in the maximum jet velocity in a first approximation has been derived. The comparison of the theoretical calculations with the experimental data has shown a good agreement
