Résumé : Fluid mechanics describes the physical phenomena of fluids which are often governed by partial derivative equations namely the continuity equation and the Navier-Stokes equation. The resolution of these equations using conventional methods encounters certain difficulties when it comes to dealing with problems where the geometry of the medium is complex or when there are several phases of a fluid or several fluids [TAO 16]. The current trend is towards a new approach to simulation research [CFD], which has gained a lot of popularity in recent years, it is called in English
"Lattice Boltzmann Method" (LBM), which is a relatively new development in the Computational fluid dynamics [CFD]. The lattice Boltzmann method is a method of fluid dynamics (CFD). Instead of the Navier-Stokes equations, the Boltzmann discrete equation is solved to simulate the behavior of fluids using a collision-propagation scheme. In this work, the LBM was integrated in a python code in order to simulate in 2D the behavior of a pipe flow against an obstacle, which will be used later to determine in the pipes the most solicited zones (maximum velocity and maximum pressure) to better size both the pipe and its accessories (valve, etc.) and prevent their rapid degradation.
