- Pressure Loss Coefficient of Screwed Elbow in Pulsatile Flow
説明
Demand of energy saving in various industrial fields is becoming increasingly important in recent years. The evaluation of the consumption energy in pneumatic piping systems is also becoming important. Energy losses in pneumatic piping systems are caused by pipes and various fittings that include screwed elbows, connectors, etc. Although the loss coefficient of screwed elbows in steady flow is well studied, very few studies have been made for its evaluation in unsteady flow. This paper examines the dynamic characteristics of the loss coefficient of a screwed elbow (nominal size: 1/2 B) in pneumatic unsteady flow, experimentally. This study confirmed the pressure change of a screwed elbow in turbulent pulsating flow up to 300 of dimensionless pulsatile frequency agree well with the calculation result assuming a steady-state loss coefficient.
