| Blowing Effects on Heat and Mass Transfer for Different Geometrical Configurations (1998) | |||||||||||
Abstract | |||||||||||
| In this paper, the blowing impact on the dynamical and thermal boundary layers is investigated through experiments and numerical simulations. Two different geometries (flat plate and circular cylinder) are separately studied. It is shown that blowing tends to thicken the boundary layers and to dramatically decrease the gradients in the immediate vicinity of the surface, leading to a strong decrease of the viscous stress and heat exchanges. Hence, the surface temperature can be lowered in case of cold blowing. This process finds applicability in the surface thermal protection area or in the flow control due to the modifications that blowing induces to the wake instabilities..
