This chapter develops and examines the abrupt contractions in pipes using OpenFOAM, an open‐source computational fluid dynamics (CFD)‐three dimensional (3D) simulation software. The development of CFD of methods for industrial use was mainly guided by the need to carry out simulations on a 3D geometric model with complex physical behavior. The chapter identifies the most stable solver in order to model a compressible, non‐viscous flow with Euler equations. It determines the equations that govern the flow dynamics of a non‐viscous, compressible fluid in a 3D planar channel. The chapter wishes to evaluate the enthalpy and mean flow rate over time and space through different positions. It discusses how the mean flow rate varies over a Cartesian domainwith conditions II for the onward and return wave. It is concluded that the structure of the mesh under the conditions II has a considerable impact on the numerical simulation regarding the behavior of the mean flow rate.
