  • Reynolds-averaged Navier–Stokes (RANS)

  • k-Epsilon

  • k-Omega

  • kOmega-SST

  • Large eddy simulation (LES)

\underline{\textbf{Compressible fluid flow on SimScale}}

Compressible Fluid Flow Analysis is commonly used where density variations have a significant influence on the investigated system. Usually, when the flow velocities exceed ~30 % of the speed of sound, compressible effects start to gain importance.

Turbulence models available in this module:

  • Reynolds-averaged Navier–Stokes (RANS)

  • k-Epsilon

  • kOmega-SST

  • Large eddy simulation (LES)

  • Smagorinsky

  • Spalart-Allmaras

\underline{\textbf{Convective Heat Transfer on SimScale}}

Convective Heat Transfer Analysis could be used to run simulations in which temperature changes in the fluid lead to density changes. Such changes in density cause the fluid to circulate under the influence of gravity.

Turbulence models available in this module:

  • Reynolds-averaged Navier–Stokes (RANS)

  • k-Epsilon

  • kOmega-SST

  • Large eddy simulation (LES)

  • Smagorinsky

  • Spalart-Allmaras

\underline{\textbf{Conjugate Heat Transfer (CHT) on SimScale}}

Conjugate Heat Transfer Analysis allows the simulation of the heat transfer between Solid and Fluid domains by exchanging thermal energy at the interfaces between them. It requires a multiregion mesh to have a clear definition of the interfaces in the computational domain. Such a mesh can be created with the Hex-dominant parametric operation in the mesh creator.

Turbulence models available in this module:

  • Reynolds-averaged Navier–Stokes (RANS)

  • k-Epsilon

  • kOmega-SST

  • Large eddy simulation (LES)

  • Smagorinsky

\underline{\textbf{Passive Scalar Transport on SimScale}}

Passive Scalar Transport Analysis type allows you to simulate the transport of a scalar quantity within an incompressible fluid flow. The core assumption of this analysis is that the species that is transported within the flow does not affect the fluid flow (therefore passive).

Turbulence models available in this module:

  • Reynolds-averaged Navier–Stokes (RANS)

  • k-Epsilon

  • k-Omega

  • kOmega-SST

  • Large eddy simulation (LES)

  • Smagorinsky

  • Spalart-Allmaras

\underline{\textbf{Multiphase Fluid Flow on SimScale}}

Multiphase Fluid Flow Analysis could be used to simulate the behavior of a mixture of fluids and their interactions. The analysis is carried out using the VoF (Volume of fluid) method which is a standard approach for the computation of multiphase systems.

Turbulence models available in this module:

  • Reynolds-averaged Navier–Stokes (RANS)

  • k-Epsilon

  • k-Omega

  • kOmega-SST

  • Large eddy simulation (LES)

  • Smagorinsky

  • Spalart-Allmaras

Multiphase Fluid Flow Analysis Examples


\underline{\textbf{Discrete Phase Model on SimScale}}

Discrete Phase Model Analysis could be used to run simulations that consist of a continuum and a discrete phase. The discrete phase is represented with particles which interact with the continuum phase. Full particle-fluid interactions could be considered. Therefore, the model is suitable for dense and dilute particle flows.

Turbulence models available in this module:

  • Reynolds-averaged Navier–Stokes (RANS)

  • k-Epsilon

  • Large eddy simulation (LES)

  • Smagorinsky

  • k-Eqn

\underline{\textbf{Potential Flow on SimScale}}

Potential Flow Analysis could be used to run simulations in which the velocity field is irrotational. This assumption is valid in several applications.
