Centrifugal pump design and analysis

AIM :- Performance diagram. Obtain the relationship between Pressure ratio and mass flow rate.

inputs:-

step 1. :- the diameter of the outer circle is 0.04

again the diameter of smaller circle is 0.02m

then created a arc as rotatory blade between the cboth circles.

number of blade = 6

then excruded at the lenth of 0.01 m

then our empeler is designed.

then crreated dia. of outer voulete at 0.045m

then ecruded it in the mid plane of thickness 0.015m

then creted the runner at the top of dia . 0.015m

then created a new wizard in which selected water as fluid for the simulation.

then defined the boundary conditions as

inlet - environmental pressure

the outlet discharge pipe is maintained at vel. 10m/s

the rotational speed of the domain is 1000rad/sec

then created new parametric study is done .

input parameter - velocity normal to the face - for 5 values 10,15,20,25,30

flow trajectories.
