    So, prediction of the turbulent effects in the flow solutions is extremely important. The main objective of this study is, therefore, to develop a 3-D parallel flow solver for turbulent flows around rotating bodies using unstructured grids, to obtain numerical solutions of Navier-Stokes equation on rotating grids. method. All parallel computations were carried out on a core Intel Xeon X server with 32GB of RAM. (*)Initial-ization refers to multigrid hierarchy initialization.

    Computational methods are now pervasive in the science of aerodynamics. Because previously existing numerical methods proved inadequate for fluid flow simulations, the emergence of computational fluid dynamics (CFD) as a distinct discipline has sparked the development of an entirely new class of algorithms and a supporting body of theory, which are the main theme of this article.   J.-S.
