Churning Oil Path Optimization Process Development - Application of Moving Particle Simulation Method to Design Process

Correlation with bench test were conductedwith different gear speed and temperature to decide adequate particle size andsimulation coefficients.

The MPS method using Particleworks, made itpossible to

1. Develop on time with optimised churning oilpath and loss
2. Minimise bench tests
3. Easily assess designs

Particleworks for Solidworks

The Particleworks for Solidworks add-in is a lite version of Particleworks allowing you to easily run simulations within the 3D CAD environment. Fully embedded into the Solidworks GUI, users can still benefit from the mesh-free CFD particle method for free surface flow simulations with large deformations.

The user friendly operation means that engineers are able to evaluate product designs in the front-loading stage with ease.

The difference between Solidworks Flow Simulation and Particleworks

Particleworks for Solidworkscapability include;

• ​Core applications such as Splashing, Mixing and Spraying
• Support for upto 0.5 million particles
• Up to 8 core systems supported
• Key operable parameters accessed through the Solidworks GUI

Particleworks features not supported in the Solidworks add-in include;

• GPU calculations
• SimultaneousJobs
• Floatingenvironments
• Multiphysics systems
• Customisation

Particleworks for ANSYS

The Particleworks for ANSYS direct integration is now available to improve the interaction between ANSYS products and Particleworks, allowing users to gain product design insights faster than ever before.

The coupling of Particleworks withthe ANSYS fluid simulation solution, complements the ability to simulaterealistic air-liquid behaviour, empowering ANSYS structural users to simulatecomplex multi-physics phenomena.

For users of ANSYS Workbench, theenvironment enables the calculation of structure deformation caused by fluidpressure and structure heat transfer by use of the Heat Transfer Coefficient(HTC).

Particleworks can also beintegrated with ANSYS Mechanical for calculating e-drives and the cooling ofinternal combustion engines. In this case, the heat transfer and cooling datafrom the Particleworks simulation can be automatically and seamlesslytransferred to ANSYS Mechanical to take into account the efficiency of the oilcooling. Allowing ANSYS Mechanical users to accurately predict the temperatureand stress of the e-drive or piston.

In addition, Particleworks cantransfer the mechanical pressure distributions during a transient process, suchas the pressure produced by the sloshing of fuel or any other liquid in a tank,or the forces produced by water, mud or snow on the bumper of car to ANSYSMechanical.

Particleworks

Enquire about Particleworks and find out how to utilise the mesh-less Moving Particle Simulation method to model and simulate large-scale problems without overwhelming resources for liquid/fluid flow.

Allowing Computational Fluid Dynamics (CFD) Users to be able to better process and simulate designs faster with reduced resource consumption, especially when traditional CFD is considered unfeasible to use for their problem.

The powerful visualisation capabilities in Particleworks also enables Engineers who rely on tests to accelerate designs and further understand fluid behaviour that cannot be seen during physical testing.

Particleworks lets you import files directly from CAD software, avoiding the complicated and repetitive mesh generation needed for conventional CFD software.

Main Benefits

• Achieveimproved accuracy of free surface flow
• Overcomecomplex boundary geometries with flexible boundary conditions
• Accelerateflexible fluid power/fluid rigid body integrations
• Understand themodularity of chemical reactions and mixing
