STABILITY OF HADLEY CIRCULATIONS IN A VISCOELASTIC FLUID WITH DEFORMABLE FREE SURFACE

摘要

This paper deals with linear convective stability analysis of Oldroyd B fluid in a thin horizontal layer with a deformable free surface. The lower surface of the layer is in contact with an adiabatic rigid plate and the upper deforrnable surface is subject to a temperature dependent surface tension. The eigenvalue problem is solved by the Chebyshev Tau-QZ method and the results for various different forms of upper surfaces are presented.
