TwinMesh for Reliable CFD Analysis of Rotary Lobe PumpsCombining TwinMesh and ANSYS CFD offers engineers a unique, efficient and fast workflow for transient, three-dimensional computational fluid and thermal simulation (cfd) of rotary lobe pumps.
Design Engineers of Rotary Lobe Pumps Must:
- Have deep insights into the details of the machine behavior
- Analyse the impact of different operation requirements (e.g different fluid viscosities, pressure difference, speed, etc.)
- Be able to answer specific customer demands
- Produce fast and reliable answers
Thanks to our novel software TwinMesh real virtual product development is now available for rotary lobe pumps! TwinMesh and ANSYS CFD together allow for efficient and reliable CFD analysis of rotary lobe pumps.
No More Numerical Limits
Common limitations of most CFD software packages such as
- limited physicical models or mesh motion features,
- insufficient mesh resolution or mesh topology
- numerical errors due to bad mesh quality while remeshing
- numerical errors due to frequent interpolation or
- numerical and physical limits due 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 CFD. The high quality meshes from TwinMesh result in reliable and stable CFD simulations of rotary lobe pumps at moderate model sizes and moderate calculation times for transient analysis.
Reliable CFD Analysis of Rotary Lobe Pumps:
CFD analysis results generated with TwinMesh and ANSYS CFD provide engineers of rotary lobe 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 ANSYS CFD together make a reliable, modern, and state-of-the-art engineering tool, which allows for fast, reliable and efficient analysis and optimisation of lobe pumps.
Increase machine performance, efficiency, and durability by a better understanding of complex phenomena inside your machine.
