Dynamics Analysis and Testing of Transonic Flows in Main Nozzle of an Air-Jet Loom

Abstract:

On the basis of fluid dynamics, this paper deduced the pull force formula of main nozzle on air-jet loom and introduces a method of experiment to test the airflow velocity in the exit of nozzle. The effect of different parameter structure of main nozzle on the pull force had been studied. It was observed that the inlet of thread tube was a bottleneck of main nozzle and the main development of main nozzle lengthens the thread tube. The theoretical findings were found to be in good agreement with experiment finding and this verified that the formula for pull force was reasonable.
