Abstract

Blade thickness and blade height are the most influencing parameters on the performance of pump. The fluid flow passage can be optimised by the blade thickness. Energy consumption by pump is reduced by employing appropriate blade height. The objective of the present study is to optimise the blade geometry, viz. thickness and height. The duty parameters considered in the present study are flow rate (Q) 5000 LPH, Head (H) 28–26 m and speed 6000 rpm. Numerical simulations are carried out to study the pump performance. Three-dimensional, steady-state flow equations are solved in ANSYS CFX along with Reynolds-averaged Naiver–Stokes (RANS) equations with standard shear stress transport (SST) turbulence models. The results showed that energy consumption decreases with blade height.
