project on centrifugal pump analysis

In this challenge, the 3D model for a centrifugal pump is created and then flow simulation is run and various parameter variations are studied.

Centrifugal pump design dimensions in mm

• Diameter of the Volute casing is 90 mm.
• Thickness of the Volute casing is 20 mm.
• Rotar blade diameter is from 40mm to 80mm.
• Diameter of the inlet suction cylinder is 30 mm.
• Length of the inlet suction cylinder is 70 mm.
• Diameter of the delivery pipe is 12 mm.
• Length of the delivery pipe is 120 mm.

Water is the working fluid in this simulation.

Boundary conditions

• Inlet suction pipe is maintained at environmental pressure [101325 Pa]
• Outlet discharge pipe is maintained at some velocity [m/s].
• A domain or cylindrical structure is made around the rotar which completely covers the rotar from all the sides.
• The dimensions of domain, diameter 85mm and thickness 15mm.
• The rotational speed of this domain is 1000 rad/sec.

• Velocity variation plot for various values of outlet Velocity
