Flow Field Simulation of the Solo-Supported High Pressure Gas Device of Double-Layer Air Jet Looms

Abstract:

A research program is currently underway with the purpose of developing a double-layer air jet looms with solo-supported gas device. Issues related to the design and feasibility analysis of the solo-supported high pressure gas device are discussed. The results of simulations show that assistant nozzle is necessary during weft insertion motion, but too many assistant nozzles would cause the flow velocity reduce. And it is confirmed that flow channel with one main and four assistant nozzles is one of the best designs to keep the flow velocity at the middle line of flow channel more than 90m/s and make the loom work swimmingly.
