Impeller and volute design and optimization of the centrifugal pump with low specific speed in order to extract performance curves
Now a day centrifugal pumps are vital components of industries. Certainly, one of the most important specifications of centrifugal pumps are the performance curves. In the present work, performance curves of a centrifugal pumps are obtained by Computational fluid dynamics (CFD) and as an outcome, CFD results compare by practical curves. At the first step impeller and volute are designed with tw...
متن کاملExperimental Study and Three-Dimensional Numerical Flow Simulation in a Centrifugal Pump when Handling Viscous Fluids
In this paper the centrifugal pump performances are tested when handling water and viscous oils as Newtonian fluids. Also, this paper shows a numerical simulation of the three-dimensional fluid flow inside a centrifugal pump. For these numerical simulations the SIMPLEC algorithm is used for solving governing equations of incompressible viscous/turbulent flows through the pump. The k-ε turbulenc...
متن کاملNumerical Study of the tongue geometry effects on the cavitation and performance of a centrifugal pump in off-design conditions
In this study, the effects of the volute tongue geometry variation on the head, efficiency, velocity distribution and cavitation structure of a centrifugal pump in the steady flow behavior under off-design conditions have been investigated. Numerical simulation modeling based on the turbulence model with a hybrid grid is used to simulate the flow within the modeled pump. The flow is simulated ...

Numerical Calculation of the Flow in a Centrifugal Pump Impeller Using Cartesian Grid
The simulation of the three-dimensional turbulent flow in turbomachines is currently based on the solution of the Reynolds Averaged Navier Stokes equations. A considerable computational effort usually goes to the mesh generation process due to the complexity of the impeller geometry. The use of Cartesian grids combined with a numerical technique for solving partially blocked cells is presented ...
