Abstract
The development of energy saving system with pressure regulator has recently been received interests. Since the internal geometry in the pressure regulator is small and complex, the frictional loss in it is critical. In this study, the pressure loss with tip size, tip position, and mass flow was investigated using numerical approaches(CFD). The aimed reduction in pressure were achieved as the ratio of t/T was more than 0.8. In addition, there was no effect of the tip position.
