TwinMesh for Reliable CFD Analysis of Vane Pumps

Combining TwinMesh and ANSYS CFX offers engineers a unique, efficient and fast workflow for transient, three-dimensional computational fluid and thermal analyses (cfd) of vane pumps.

Design engineers of vane pumps have to:

  • Have deep insight into their machine behavior and existing limits,
  • Analyse the impact of changing operation requirements (e.g other fluid viscosity, different revolution speeds, impact of external temperatures, etc.),
  • Be able to answer specific customer demands and
  • Produce fast and reliable answers.

Thanks to our software TwinMesh virtual product development is now available for vane pumps!

No More Numerical Limits

Common limitations of CFD software packages such as limited physics, insufficient mesh resolution or numerical errors due to bad mesh quality or interpolation errors or overlapping mesh method are redundant for the TwinMesh approach.

Using structered grids from the TwinMesh software users get access to the full capacity of CFD modelling available in ANSYS CFX. The high quality meshes from TwinMesh result in reliable and stable CFD simulations for vane pumps at moderate model sizes and moderate calculation times for transient analysis.

What Engineers Can Expect:

CFD analysis results generated with TwinMesh and ANSYS CFX provide engineers of vane pumps with essential information such as:

  • Velocity, pressure, and temperature fields within the working chamber
  • Flow rates and mass flow at user defined operation points,
  • Torques, moments, forces and machine efficiency (CoP),
  • Leakage and losses,
  • Pulsation behaviour of the machine,
  • Impact of design changes,
  • Duration and magnitude of acoustic sources (emission).

TwinMesh and ANSYS CFX together make a reliable, modern, and state-of-the-art engineering tool, which allows for fast, reliable and efficient analysis and optimisation of vane pumps.

Preview of Mesh Interpolation and Non-Reflective Boundary Conditions in TwinMesh 2018

The next preview of new features in TwinMesh 2018: we implemented a mesh interpolation method in User Fortran. So far, the time step size of the CFD simulation has to be set according to the desired revolution speed and the prescribed angle increment of the pre-generated meshes from TwinMesh. Now it is possible to set an arbitrary time step size, and the corresponding mesh is calculated with a spline interpolation between the pre-generated meshes at run-time.

Preview of Non-Reflective Boundary Conditions in TwinMesh 2018

Preview on new features in TwinMesh 2018: we have implemented non-reflective boundary conditions (NRBC) in ANSYS CFX via User Fortran in a stable and robust way so that they can be used for positive displacement compressors instead of the standard openings which are reflective (RBC). While RBC lead to standing waves, especially at pressure side with mass flow strongly pulsating and even flow reversal, NRBC allow pressure fluctuations from pressure port to travel to the outlet and leave there without any artificial reflections so that mass flow is more uniform and realistic.
