In this book the CFD analysis of a centrifugal pump is done using k-ε
turbulent modeling and SIMPLEC algorithm from which the velocity and
pressure contours are plotted for different operating conditions. In
this work the mass flow rate is varied three times for two different
fluids that are water and fuel oil. First the mass flow rate is
decreased by 10% from the initial value of mass flow rate and then
increased by 10% from the initial value of mass flow rate. Using the
results of varying mass flow rate the efficiency at different mass flow
rate is calculated. The results are compared with the theoretical
results. Then the theoretical and software results are plotted in the
operating characteristics curves and are verified. The deviation
produced among them nearly 10% to 15 % is permissible. Then the
rotational speed (RPM) is changed by decreasing and increasing by 10%
and results are compared with the theoretical results and verified
through characteristics curves. After the flow analysis the maximum
pressure acting on the blades for the maximum efficiency in case of
water and fuel oil are calculated from CFD analysis and the fatigue
analysis (FEA) of the centrifugal pump
