 ### 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. ### Courant number

Courant number in CFD simulations The Courant number is a non-dimensional number named after the mathematician Richard Courant. The Courant number can be used in Computational Fluid Dynamics (CFD) simulations to evaluate the time step requirements of a transient simulation for a given mesh size ### CFD modelling

Computational Fluid Dynamics (CFD) modelling is the process of creating a computer model to solve an engineering problem involving fluid flows. The CFD model is a representation of the fluid dynamics in a specific application, which are solved using a numerical algorithm to obtain the ### 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?
