CFD computational domain

CFD computational domain definition A Computational Fluid Dynamics (CFD) domain is the portion of space where the solution of the CFD simulation is calculated. The computational domain needs to be discretised into a computational grid (or mesh) to solve the discretised equations of fluid flows.

Reynolds number effect on vortex street in cloud pattern

Reynolds number

The Reynolds number is a non-dimensional number defined as the ratio between the convective forces and the viscous forces of a fluid flow, and can be used to describe its nature, indicating whether it is laminar, transitional or fully turbulent. What is the Reynolds Number?

Turbulence models in CFD

Turbulence models in Computational Fluid Dynamics (CFD) are methods to include the effect of turbulence in the simulation of fluid flows. The majority of simulations require a turbulence model as turbulent flows are prevalent in nature and in industrial flows and occur in most engineering applications.
