| The article conducts an analysis of flow around spherical and non-spherical elements for a wide range of Reynolds numbers using direct numerical simulations based on the indefinite heat conducting equation (3D) and the Navier-Stokes equation. The research focuses on the influence of the shape of the element on the drag coefficient of the flow. It has been found that the total air drag coefficient around the considered elements depends on their shape and Reynolds number. The drag coefficient for the particular element example (sphere) has been compared with the experimental data. Further results have been presented in this paper. |
