TwinMesh for Reliable CFD Analysis of Scroll Compressors and Scroll Expanders
Combining TwinMesh and ANSYS CFD offers engineers a unique, efficient and fast workflow for transient, three-dimensional computational fluid and thermal simulation (cfd) of scroll compressors, expanders and scroll-typed superchargers
Developers of Scroll Compressors and Expanders Have to:
- Analyse the impact of varying operation requirements (e.g. impact of external temperatures, rotation speed).
- Get well knowledge of their machine behaviour in detail (e.g. cooling, clearance flow, etc.)
- Be able to answer specific customer demands (e.g. operating range, noise reduction) and
- Produce fast and reliable answers.
Thanks to our novel software TwinMesh virtual product development is now available for scroll compressors, expanders and scroll-typed superchargers! TwinMesh and ANSYS CFD together allow efficient and reliable CFD analysis of scroll compressors and expanders.
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 and mesh interpolation errors or due to numerical limits of overlapping mesh methods are redundant for the TwinMesh approach.
Using structured grids from the TwinMesh software users get access to the full capability of CFD modelling available in ANSYS CFD. The high quality meshes from TwinMesh result in reliable and stable CFD simulations at moderate model sizes and moderate calculation times for transient analysis. Even for multiphase simulation such like oil-injectes or water-cooled scroll compressors and expanders.
Reliable CFD Analysis of Scroll Compressors and Expanders
CFD simulation results of scroll compressor and expanders designs generated with TwinMesh and ANSYS CFD software provide design engineers 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 different operation points
- Torques, moments, forces and machine efficiency (CoP)
- Leakage and losses
- Pulsation behaviour of the machine
- Mechanical wear, lubrication and cooling
- Duration and magnitude of acoustic sources (emission)
TwinMesh and ANSYS CFD together make a reliable, modern, and state-of-the-art engineering tool, which allows for fast, reliable and efficient analysis and optimization of scroll compressors and scroll expanders.
