Abstract : An analysis is presented for thermal stratification of a subcooled liquid draining from cylindrical flat-bottomed vessels with both wall and bottom heating. It is based on natural convection boundary layer flow along the vertical walls in the unstratified region, assumes time invariant dimensionless temperature profiles in the stratified region and assumes the bottom heat rate to mix instantaneously with the uniform temperature unstratified region. For a non-draining vessel the analysis predicts an asymptotic overall temperature profile to be approached, i.e., asymptotic stratified layer thickness and asymptotic temperature difference between the surface and the unstratified region.
