Description
Description
This project is related to the numerical simulation of the Internal Gear Pump using Ansys Fluent software. A pump is a mechanical device for moving and transferring all liquids from one place to another. In this way, by increasing the pressure, pumps cause liquids to move to a higher height (by increasing the head) and even lower (such as tanks).
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 gear pump is one of the most common pumps to increase the hydraulic power of a fluid. Gear pumps move liquids using gears. These gear pumps are made of two types of internal and external gears.
Internal gear pumps consist of two gears that rotate in the same direction, so one gear is inside the other. When two gears make contact with their teeth, fluid is trapped. Now, when the teeth are separated from each other due to rotation, high-pressure fluid is rotated through the ribs to the outlet.
In these internal gear pumps, a crescent between the inner and outer gear directs the flow path to the outlet.
We modeled the geometry of the project using Design Modeler software.
The geometry is related to an internal gear pump. The computational domain includes the internal space of the pump with two non-concentric gears inside each other. A crescent is also placed in the space between two gears.
Then we meshed the model with Ansys Meshing software. The model mesh is unstructured, and the number of cells equals 50,106.
Internal Gear Pump Methodology
This project simulated the water flow inside an internal gear pump.
We aim to model the rotation of two gears inside the pump. The gears’ rotation changes the fluid’s behavior in the pump momentarily. So, the mesh of the computing domain deforms over time.
Then we used the Dynamic Mesh Model. We generally use a dynamic mesh whenever we have a moving boundary or a deforming zone.
Here, two gears are rotating in the same direction. So this causes the mesh to deform over time. Therefore, we define a Rigid Body to define the rotational motion of the gears. We use a user-defined function (UDF) to define the motion of the rigid body.
According to the rotational motion of the gears as a rigid body, the mesh zone around the gears 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.
Internal Gear Pump Conclusion
After the solution, we obtained pressure, velocity contours, and velocity vectors. Because the gears rotate over time, we obtained the velocity and pressure contours animation.
The results show that this gear pump is working correctly. This pump can transfer the fluid well and increase the fluid’s pressure. The fluid is trapped in the space between the gears in contact. Then this fluid is pushed towards the outlet with high pressure.

I found the detailed aspects of dynamic mesh handling fascinating. Would you mind explaining a bit more about how the Rigid Body motion in the simulation is coordinated with the Dynamic Mesh to faithfully replicate the pump action? Just looking to get a sense of the kind of user-defined functions you might employ for that.
MR CFD Support –
In this simulation, the Rigid Body motion of the gears is coordinated with the Dynamic Mesh to accurately replicate the internal gear pump’s performance. This coordination is achieved through a User-Defined Function (UDF) that prescribes the rotation of the gears. UDFs in ANSYS Fluent are written in C programming language and are used to customize the motion, boundary conditions or add various enhancements to the simulation. For the gear pump, the UDF would control the angular velocity and position of the gears in relation to time, synchronising the mesh deformation with the gears’ rotation ensuring that the fluid motion and pressurisation within the pump occur realistically as would be expected in an actual pump operation.
