Flow over a sphere placed above the surface is investigated in this work with a proper numerical technique. The Reynold’s number based on the sphere diameter is taken as Re ≈ 3×104 i.e. the flow is fully turbulent. The standard k - ε and the standerd k - ω turbulence models are utilized to capture the flow behavior of the sphere. An unstructured mesh topology had been generated to mesh the sphere and its surrounding domain. Various fluid properties of the flow phenomena for the two turbulence models with proper contours and diagram were showed and discussed in details. The downstream complex flow phenomena are observed for this turbulent flow. The results and comparison between this two turbulence models showed better agreement for the present numerical technique.
