What is the difference between MPS and SPH?
While both (Moving Particle Simulation) MPS and (Smoothed Particle Hydrodynamics) SPH are particle-based, meshless CFD methods, there are large differences between them. The SPH method was originally developed to simulate compressible gasses where are the MPS method was developed to simulate incompressible fluids. Adaptations have been made to the SPH method to allow for incompressible fluids but due to this, the time step required is far smaller than is required in the MPS method. As well as this, most SPH tools cannot calculate HTC (Heat Transfer Coefficient) so if you are looking to simulate the cooling of a component due to a fluid, the clear choice is the MPS method.
Why calculate the HTC instead of the temperature of a component?
Thermal time scales are so much longer than fluid time scales. When simulating the cooling jet of a piston or the oil flow around the windings of an E-Motor, we usually achieve a steady fluid flow within 5 seconds. The piston/windings however may not achieve thermal equilibrium for a further 5 – 10 minutes. Simulating the fluid for this entire time is a waste of computational time. Instead, we suggest simulating the fluid until it achieves a steady state and exporting the HTC on the surface of the components. This HTC surface then becomes the boundary condition for a Finite Element Analysis simulation to calculate the full thermal profile throughout the component without explicitly simulating the fluid for the entire time.
How will Particleworks save me time and money?
Physical testing is an expensive and time-consuming activity. Prototypes cost a lot to produce, testing is limited and requires experienced engineers and test facility availability and if issues are not discovered until the physical tests, we need to begin the entire design process all over again. By replacing physical testing with virtual prototyping (using Particleworks) we can validate and improve designs at the start of the design process instead of at the end. This cuts down on the number of prototypes that need to be produced and tested and allows more design iteration to be analyzed to find the optimal design rather than the first design to pass the test.
