Analysis and Simulation of the Fluid Field in Thermal Water-Jet Nozzle based on ANSYS FLUENT & ICEM CFD

Thermal water jet is an important part of the synthetically de-icing equipment designed to cut the frozen ice and snow on the public facilities. The inner structures of the jet nozzle, such as the conical and straight conical nozzles, have a crucial influence on the final efficiency of the cutting. In order to figure out the effect of these two kinds of nozzle structures to the jet fluid, and provide some strong references for the structure optimization, this paper synthetically uses ICEM CFD and ANSYS FLUENT software to analyze the fluid of the conical and straight conical jet nozzles. The results show that: as the initial conditions are determined, the conical nozzle has a higher speed and longer isokinetic core zone of the flux than that of the straight conical nozzle, and the speed changes more dramatically. However, the straight conical nozzle has a more stable speed, and lower operating vibrations. Through repeated indoor experiments, the simulation results are demonstrated.
