Numerical simulation study of flow field of centrifugal pump based on variable speed
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 4
Abstract
In order to study the variable speed influent to the inner flow field of centrifugal pump, we selected three pump speed, 1500r/min, 2200r/min, 3200r/min, as working condition to conduct on fluid dynamics numerical simulation. The simulation results indicated that with the speed increasing or decreasing, the inner flow field of centrifugal pump has different degrees of changing. Furthermore, at the working condition of 1500r/min and 3200r/min, the inner flow passage have very obvious difference, there are bigger pressure and velocity gradient in the local region. This centrifugal pump has a good performance of working in this speed range. Keywords: Centrifugal Pump, Variable Speed, Flow Field, Numerical Simulation
