Description
Summary:Numerical simulations of a linearly stratified diffusive flow past an impulsively started sphere are described. The impulsive start is perpendicular to isopycnal surfaces. The equations are transformed to generalized coordinates and then approximated by a finite difference scheme over a suitable grid which resolves both the diffusive and viscous boundary-layers. The results are compared with experimental evidence.
