Abstract
In order to study the influence on the characteristics of the jet of different spacings of multi-hole nozzles, the standard k-e turbulence model and the pressure implicit with splitting operator (PISO) algorithm of Fluent software were adopted to research the velocity distribution under different pressures of two jets of the nozzle at different spacings, and the results were compared and analyzed. The results show that the existence of the entrainment phenomenon has played a significant role in jet development, and the two key factors influencing the entrainment effect are the jet exit velocity and the distance between the nozzle.关键词
