Resum
Direct and large-eddy numerical simulations have been performed for a heated sphere at Reynolds numbers 200, 300, 500, 750, 1000 and 104, in the context of the development of a spherical wind sensor for Mars atmosphere intended for missions after Rover 2020. A lowdissipation ¿nite element scheme implemented in the multi-physics code Alya has been used to do so. The main heat transfer and aerodynamic parameters are presented, followed by detailed analysis of the wake and boundary layer developme...
