Abstract
A centrifugal pump is used for water trubine from the pump channels. The technology of the pump as turbine is expected to provide an alternative energy solutions for the manufacture of micro hydro small scale and costs more economical and affordable.
The purpose of the study is know the influence of modelling the geometry on the impeller centrifugal pumps that can affect the performance of Pump As Turbine (PAT) with the value of the surface roughness of the impeller 0,16mikrometer using forward blade close impeller model. The methode of research analysis design and fluid flow at the impeller by use CFD software.
Keywords: Pump As Turbin, Computational Fluid Dynamics, backward impeller
