Ram Pump Project Description
In this project, a ram pump has been simulated by Ansys Fluent software. In this simulation, a mesh motion model with an angular velocity of 1 radian per second has been used, and the input speed has Water is one m/s, and at the outlet, water is discharged at atmospheric pressure.
Geometry & Mesh
The two-dimensional geometry of this project has been produced with Spaceclim software. The length of the calculation domain is 220 cm, and its height is 153 cm.
The meshing of this project has been done with Ansys Meshing software, and the type of elements is unstructured. Also, the total number of elements is 325579.
Ram Pump CFD Simulation
- Due to the incompressibility of the flow, the pressure-based solver method has been selected.
- The simulation is transient.
- The gravity effect is considered equal to -9.81 m.s-1on Y-axis

Ram Pump Results
At the end of the simulation, we can see the velocity and pressure meters. It is clear that when both valves are half-closed, this suffocation increases the pressure in the pipe and when one of the valves, The face is entirely open. The other valve is completely closed. All the inlet fluid comes out with the high pressure created by the open side.
