Résumé : Aerodynamics is defined as the science of handling a fluid that is often the air interacting with a structure. In this science, the number of searches is increasing and growing rapidly due to the rapid evolution of Computational Fluid Dynamics (CFD) that has been driven by the need of faster and more accurate methods. The mesh, in these numerical simulations, plays a preponderant role because it makes it possible to discretize the system of equations to be solved and thus to represent the geometry studied. However, there are many problems for which it is advantageous to solve the equations in a moving frame. The Dynamic Mesh (DM) model is used to model flows in which the shape of the domain changes over time due to movement on the boundaries of the domain. In this paper, this technique of the moving mesh was presented and applied for the simulation of a two-dimensional transonic flow over a NACA0012 airfoil using ANSYS/Fluent, validated with the provided experimental data, and the results of this technique are then compared. The flow to be considered is compressible and turbulent and the solver used is the density based implicit solver, which gives good results for high speed compressible flows.
