Abstract

The steady, uniform, horizontal flow of a vertically stratified, non-diffusive fluid over a sphere is considered. A correction to the Stokes drag formula is obtained which is valid for small values of a stratification parameter α, Re [Lt ] |α| 1/3 and Fr2 [Lt ] |α|−1/3. To the order of the calculations, the sphere has no tendency to rotate, nor does it experience a lift force.
