Abstract

Results of investigations on gas jet structure and selection of the optimal nozzle configuration are presented. Free flow from the nozzle and the flat obstacle overflowing were considered. The optimal distance h from the nozzle to the obstacle was determined. The optimal flow rate and gas pressure in the nozzle outlet and in the area in front of the obstacle were found. The flow rate distribution in different cross-sections is presented. Experimental results were employed in the formation of a mathematical model.
