Optimal design of nozzle for filter bag cleaning device of combined air-conditioning based on fluid mechanics

Abstract

Nozzles are terminal accessories and important parts of equipment for spraying high speed water flow. The shape of nozzle is the main reason that affects the change of pressure and velocity field. For this reason, this paper uses ANSYS software to monitor the pressure and velocity distribution of the internal flow field of nozzle and the high-speed flow field outside the nozzle. In the paper are compared and analyzed the flow field changes due to different nozzle shapes and the influences of various parameters on the nozzle flow field, providing a reference for the rational use of the structural parameters of nozzle.
