Tubing Cleaning Nozzle Assembly Structure Improvement and Numerical Simulation

Abstract:

The installation position of nozzle directly affect the efficiency of high pressure water jet cleaning. In order to improve the cleaning efficiency, the paper establish the three-dimensional structure and numerical model of the original nozzle assembly and the spiral nozzle assembly. The numerical simulation results show that, on the same boundary conditions, the effective hit range of the spiral nozzle assembly is greater and more uniform than that of the original nozzle assembly.The effective surge pressure of the spiral nozzle assembly is larger than that of the original nozzle assembly, spiral nozzle assembly can can reduce the blind cleaning area and improve the cleaning efficiency.
