TwinMesh for Reliable CFD Analysis of Lobe Blowers and ExpandersCombining TwinMesh and ANSYS CFX offers engineers a unique, efficient and fast workflow for transient, three-dimensional computational fluid and thermal analysis (cfd) of roots-type blowers, superchargers, and expanders.
Design Engineers of Roots-typed Blowers Have to
- Analyse the impacts of different operation requirements (e.g operating range, rotor speed, etc.)
- Get a deep understanding of the details of their machine dynamics (gap flow losses, thermal effects)
- Be able to answer specific customer demands (CoP, noise reduction, etc.) and
- Produce fast and reliable answers.
Thanks to our novel software TwinMesh real virtual product development is now available for roots-type superchargers, blowers and expanders! TwinMesh and ANSYS CFX together allow for efficient and reliable CFD analysis of lobe blowers and expanders.
No More Numerical Limits
Common limitations of CFD software packages for lobe blowers such as limited physics, insufficient mesh resolution, numerical errors due to bad mesh quality or interpolation errors or limits due to the use of overlapping mesh method 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 CFX. The high quality meshes from TwinMesh result in reliable and stable CFD simulations for lobe blower geometries at moderate model sizes and moderate calculation times for transient analysis.
Reliable CFD Analysis of Lobe Blowers and Expanders
And what can design engineers of lobe blower ore expander geometries expect from CFD simulation? CFD simulation results generated with TwinMesh and ANSYS CFX provide design engineers of roots blowers, expanders and roots-type superchargers 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 CFX together make a reliable, modern, and state-of-the-art engineering tool, which allows for fast, reliable and efficient analysis and optimization of oil-free, oil-injected and water-cooled roots-type machines.
Increase machine performance, efficiency, and durability by a better understanding of complex phenomena inside your machine.
