Description
Description
This project is related to the numerical simulation of the Diaphragm Pump using ANSYS Fluent software. A pump is a mechanical device for moving and transferring all liquids from one place to another. The pump takes mechanical energy from an external source, such as a motor, and transfers it to the fluid passing through it. As a result, the energy of the fluid increases after leaving the pump.
The energy transfer to the pump fluid is done in two dynamic and displacement methods. Therefore, pumps are divided into positive displacement pumps and dynamic or non-positive displacement pumps. Positive displacement pumps are divided into two groups: rotary (such as gear, lobe, and vane) and reciprocating (piston and diaphragm).
A diaphragm pump is one of the pumps to increase the hydraulic power of a fluid. Diaphragm pumps use a composite membrane, which flexes up-down over a water flow.
The pump membrane has an up-and-down reciprocating motion. When the membrane moves up, the liquid flow is sucked from the intake valve, and when the membrane moves down, the liquid flow is pushed towards the outlet valve.
In this project, we simulated the water flow inside a diaphragm pump. We aim to model the reciprocating motion of the membrane inside the pump. The gears’ reciprocating motion momentarily changes the fluid’s behavior in the pump. So, the mesh of the computing domain deforms over time.
We modeled the geometry of the project using Design Modeler software. The geometry is related to a diaphragm pump. The computational domain includes the internal space of the pump with a moving membrane. Then we meshed the model with ANSYS Meshing software. The model mesh is unstructured, and the number of cells equals 222,986.
Diaphragm Pump Methodology
In this project, the Dynamic Mesh Model was used. We generally use a dynamic mesh whenever we have a moving boundary or a deforming zone.
Here, a wall creates a wave motion. So this causes the mesh to deform over time. Therefore, we define a user-defined function (UDF) to define the wavy motion of the wall. To apply the wave motion to the wall, we must use the Grid Motion UDF.
According to the reciprocating motion of the membrane as a rigid body, the mesh zone near the moving membrane is deformed. So, for this zone, we use the Deforming option.
Due to the nature of this modeling, fluid behavior is time-dependent. Hence, we use the unsteady (Transient) solver.
Diaphragm Pump Conclusion
After the solution, we obtained pressure and velocity contours. Because the membrane moves over time, we obtained the animation of the velocity and pressure contours.
The results show that the pressure and velocity constantly change under the influence of the reciprocating motion of the non-stationary membrane. The reciprocating motion causes suction from the intake valve and compression to the outlet valve.

Ivory O’Conner –
After reading about the Dynamic Mesh Model used, can you clarify how the UDF guides the deformation of the computational mesh over time?
MR CFD Support –
Certainly. A User-Defined Function (UDF) is prescribed to mathematically describe the movement of the diaphragm inside the pump. This function is then incorporated into the Dynamic Mesh Model, which is responsible for continuously updating the mesh in response to the wall’s wave-like motion. The motion defined by the UDF involves parameters such as displacement, velocity, and acceleration of the membrane, ensuring an accurate representation of its reciprocating movement is captured in the mesh deformation process.
Karine Rosenbaum –
Is it possible to observe the different stages of the pumping cycle through the output provided, like the suction and discharge phases?
MR CFD Support –
Yes, the simulation provides animated output that illustrates the pressure and velocity changes within the pump, hence you can observe the different stages of the pumping cycle including the suction when the membrane moves up and the discharge phases when it moves down.

This product is incredibly extensive! The dynamics of the diaphragm pump were well-explained, and the simulation provided clear insights into the performance. Can ANSYS Fluent capture the fluid-structure interaction in cases like the deformation of the diaphragm, or is a different software required for that part of the simulation?

Yes, ANSYS Fluent can simulate fluid-structure interaction (FSI) through its coupling with ANSYS structural tools, like Transient Structural, via System Coupling. The fluid dynamics and the structural deformation, as in the case of a diaphragm pump’s membrane, can be effectively captured, providing comprehensive insights into the behavior of the pump during operation.

Verna Nicolas –
I was curious, when observing the complete CFD simulation, what specific part of the pump shows the most significant amount of deformation due to the membrane’s reciprocating motion? Could you clarify which area is most affected by this motion in terms of structural integrity?
MR CFD Support –
In the Diaphragm Pump simulation, the most significant deformation occurs in the mesh zone nearest to the reciprocating membrane. This is because the membrane’s movement directly affects the shape and volume of the chamber space, causing the surrounding mesh to deform to accommodate the motion. This dynamic interaction is central to the pump’s operation as it leads to suction and compression at the intake and outlet valves, respectively.
Dr. Lelah Zieme V –
