(Jour. Math. & Phys. Sci., 1983, 17, 603).}, abstract={This leads to a formulation of the problem which depends upon whether the liquid layer is relatively hotter or cooler. It is found that the phenomenon of surface tension driven instability problems should not only depend upon the Marangoni number which is proportional to the maintained temperature differences across the layer but also upon another parameter that arises due to variation in the specific heat at constant volume on account of the variations in temperature. Numerical results are obtained for the problem wherein the lower free boundary is perfectly thermally conducting.}, type={artykuł}, title={Marangoni convection in a relatively hotter or cooler liquid layer with free boundaries}, keywords={Surface tension, convection, conducting, linear stability}, }
