What is SPH flow?
Simcenter SPH Flow is a rapid meshless computational fluid dynamics (CFD) software that provides designers and analysts a fully integrated workflow to easily and quickly improve their designs earlier in the development cycle. It uses the innovative smoothed-particle hydrodynamics (SPH) method.
What is SPH used for?
Smoothed-particle hydrodynamics (SPH) is a computational method used for simulating the mechanics of continuum media, such as solid mechanics and fluid flows. It was developed by Gingold and Monaghan and Lucy in 1977, initially for astrophysical problems.
How is SPH calculated?
The smoothed particle hydrodynamics (SPH) method is usually expected to be an efficient numerical tool for calculating the multiphase phenomena in compressors….ABSTRACT.
