KEYWORD: contraction angle of nozzle; length-diameter ratio of nozzle; nozzle diameter flow temperature; target distance ABSTRACT: There are series of car accidents and thousands of losses because of icy roads in cold weather. So thermal water-jet cutting and mechanical milling deicing technology is developed and researched.It means that road is jetted with hot water and then the ice is removed by using milling cutter. The shape and the parameters of the nozzle have a great effect on the test. So,the effect of straight cone nozzles contraction angle and the effect of the length-diameter ratio L/d of straight cone nozzles on jet flow field are analyzed. The nozzle diameter, the flow temperature, the target distance and the jet angle are all tested in the deicing influence and the optimal parameters are concluded.

Study on the Parameter Characteristics of Thermal Water Jet Nozzles
