Mathematical Modelling and CFD Simulation of Cavity Formation and its Elimination in Water Jet Pump Using Fluent
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
when we change inlet pressure the pressure drop is decreased and cavity is reduced or vapor pressure is reduced in efficient manner. Again when we simulate the problem by increasing both inlet and outlet pressure same phenomenon we found. Beyond the inlet pressure (7e5 pascal) no change will appear and in whole simulation system is stable in nature so fluid flow system is stable in nature which shows good results and excellent accuracy that maintain.

Beyond the inlet pressure (7e5 pascal) no change will appear and in whole simulation system is stable in nature so fluid flow system is stable in nature which shows good results and excellent accuracy that maintain. With this research we eliminate the cavity by 25 %.
