Paper Abstract

In the calculations the method of finite volumes with program packet PHOENICS 1.4 was applied. Elliptical transfer equations with standard model of turbulence were numerically solved. Three cases of flow around flat obstacle were investigated. Comparison of evaluated flow rate, pressure and turbulence energy when flowing around the plate with or without a hole was done. Highest possible values of flow rate on the symmetry axis of the system in the case of continuous hole in the obstacle were estimated. Activity of the jet in the cross-sections of nozzle outlet-obstacle and in the periphery above obstacle surface was proven. Analysis of obtained results shows the activity of introduced investigation and abilities to employ its results in projecting of conic nozzles.
