RESEARCH ON NUMERICAL SIMULATION FOR VELOCITY DISTRIBUTION OF SWIRLING TURBULENT JETS IN SPRAY IRRIGATION TECHNOLOGY

Abstract

: In spray irrigation technology, the change of the basic parameters of the flowfield has relationship directly with the coefficient of swirling intensity coefficient S, with each value of swirling coefficient differently then the distribution of parameters in flow field also variedly. Remarkably change when the coefficient of swirl intensity changes through the variables as axial velocity u, tangential velocity w; the change of radial velocity v related to turbulent intensity.
