TwinMesh for Reliable CFD Analysis of Screw Vacuum Pumps
Combining TwinMesh and CFD solvers offers engineers a unique, efficient and fast workflow for transient, three-dimensional computational fluid and thermal analysis (CFD) of screw vacuum pumps.
Design engineers of screw vacuum 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.) as well as the impact of different stator materials
- Be able to answer specific customer demands and
- Produce fast and reliable answers.
Thanks to our software TwinMesh virtual product development is available for screw vacuum pumps!
No More Numerical Limits
Common limitations of existing commercial and academic CFD software packages for screw vacuum pumps such as:
- Limited availability of physical models,
- Insufficient mesh resolution,
- Numerical errors due to poor mesh quality and interpolation errors,
- Numerical errors due to usage of overlapping meshes (e. g. immersed solid)
are redundant for the TwinMesh approach. Using structured grids from the TwinMesh software engineers of screw vacuum pumps get access to the full capability of CFD modelling available in CFD software. The high quality meshes from TwinMesh result in reliable and stable CFD simulations at moderate model sizes and moderate calculation times for transient analysis, including complex effects such as aeration, cavitation and acoustics (noise emission).
Reliable CFD Analysis of Screw Vacuum Pumps
What can engineers of screw vacuum pumps expect? CFD analysis results generated with TwinMesh and CFD software provide engineers of screw vacuum pumps with essential information such as:
- Velocity, pressure, and temperature fields within the working chambers and in axial and radial clearances
- 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
- Location and magnitude of erosion (e. g. particles, cavitation)
- Duration and magnitude of acoustic sources (emission)
TwinMesh and CFD software together make a reliable, modern, and state-of-the-art engineering tool, which allows for fast, reliable and efficient analysis and optimisation of screw vacuum pumps.
