Abstract

The energy crisis will be come soon and one of the very potentials of renewable energy is the energy usage of water for micro hydro power plant (PLTMH). A centrifugal pump is used for water turbine from the pump channels. The purpose of the study is knowing 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 0,16µm using forward blade close impeller model. The method of research analysis design and fluid flow at the impeller by use CFD software. The result of analysis showed the model backward blade close impeller with 5 blades, the impeller entrance angle β2 56.6 ° is the optimum results Velocity and pressure distribution more homogeneous.
