INVESTIGATION OF FREE SUBMERGED JETS,
Abstract
A study was made to determine the effect of the combustion process on the formation of a free jet and to obtain more accurate data on free isothermal jets formed at nozzle exits. Comparative tests with nozzles of various profiles were conducted; and additional investigations were made of a jet with uniform initial velocity fields. The total and static pressure distribution at the nozzle exits are shown. On the basis of the investigation results it was found that the following series of steps would simplify engineering calculations: (1) the total resistance coefficient of a nozzle can be found in hydraulic manuals, and the flow rate through the nozzle is then determined. The investigation results show that if the static pressure in the jet is disregarded when determining the momentum, an error of up to 12 percent may be introduced. (Author)
