Unsteady stagnation-point heat transfer during passage of a concentrated vortex

Rigby, David L.(State Univ. of New York, Buffalo, NY, United States)
Rae, William J.(New York, State University, Buffalo, United States)
Abstract: The unsteady boundary layer due to a single rectilinear vortex filament approaching a two-dimensional stagnation point is investigated. The unsteady boundary-layer equations are solved by an alternating-direction-implicit finite-difference method. Two mechanisms which cause fluctuations in heat transfer are the unsteady velocity field in the boundary layer and secondly, the unsteady total temperature at the edge of the boundary layer. The relative importance of these mechanisms is dependent upon the total temperature fluctuations relative to the imposed temperature difference.
