Water Free Full-Text Experimental Study on the Effect of
In order to study the cavitation performance of centrifugal pumps with low specific speeds under the condition of gas–liquid two-phase flow, a cavitation test rig for pumping gas–liquid two-phase flow was set up. The cavitation performance of the pump with a specific speed of 32 was studied. The variation of the head, pressure pulsation The accurate identification of the gas–liquid two-phase flow pattern within the impeller of a centrifugal pump is critical to develop a reliable model for predicting the gas–liquid two-phase performance of the Gas–Liquid Two-Phase Flow Pattern Identification

Tanks with dedicated pump pipework with both feed and return pipework connected to the tank liquid phase. This arrangement improves pump priming by allowing circulation of liquid from tank, through the pump and back to the tank, even when the pump is not running. 3.2.9 Warm end . Crank case box that drives the cold end.Centrifugal pump often operates at different working flow rates to meet engineering requirement. To better reveal the transient behavior of centrifugal pump in the process of decreasing flow rate, the finite volume method (FVM), RNG k ε turbulence model, sliding mesh technology, and user-defined functions (UDF) were employed to Transient Behavior of a Prototype Centrifugal Pump with Abrupt
