에어 제트 직기의 메인 노즐 유동에 관한 수치해석적 연구

다국어 초록 (Multilingual Abstract)

An air jet loom as one of shuttleless looms transports a yarn into warps using viscosity and kinetic energy of an air jet. A performance of this picking system depends on the ability of instantaneous inhalation/exhaust, the configuration of nozzle, the operation characteristics of a check valve, and so on. In the recent past many studies have been reported on an air jet discharged from the nozzle exit, but studies for understanding of the flow field characteristics associated with shear layer, and shock wave and boundary layer interaction in the nozzle were not conducted enough. In this paper, computational study was performed to explain the flow field in the air jet nozzle with an acceleration tube of a very small divergent angle. The result obtained from computational study show that the flow field in the air jet nozzle depends on the nozzle configuration and the length of acceleration tube.
