SPH – Smoothed Particle Hydrodynamics (en)

Flow simulation is already frequently used in the design of flow systems, whether for gases or fluids. In almost all methods used for this purpose, the system is modelled using a mesh. The mesh quality is of decisive importance for the quality of the results, whereby moving geometries can only be modelled with great effort.

Using Smoothed Particle Hydrodynamics (SPH), primarily fluids can be modelled without the need for a mesh. This enables the simulation of complex machine kinematics with detailed geometries that would not be possible with conventional methods such as CFD.

The SPH can be used to model the following scenarios, among others:

  • Liquids with different viscosities in a simulation case
  • Temperature-dependent viscosity
  • Newtonian and non-Newtonian fluids
  • Heat generation and conduction of liquids, including the machine structure
  • Complex machine kinematics and geometries
  • Coupled/interacting flows of liquid and bulk material
  • Coupled/interacting flows of air and liquid
