The Effect of Different Reynolds Number On Solid Sphere Using CFD and Its Verification

Aerodynamic behaviour of an object depends on several factors, namely shape, size and flow conditions. Thus, CFD simulations are effective engineering tools that allows major contribution to understand the conditions around object. This study aims analyse effect two typesof spherical modelsthat aresphere hemisphereon aerodynamics for different Reynolds number between 100,000 ≤ Re 800,000. Geometry models generated using SolidWorkssoftwareand numerical solution is analysedusing ANSYS CFX. The results later compared with experimental data collected from wind tunnel. At end study, nature visualized. It discovered model changes as increases. finding parallel past researchers. These forecasts should assist engineers enhance application aerodynamic hydrodynamic design.
