| Abstract: | Representing surface tension by nonlinear relationship on temperature, the boundary value problem of linear stability differential equation on small perturbation is derived. Under the isothermal wall condition the effects of nonlinear surface tension on stability of heat transfer in saturation liquid film are investigated as wall temperature is varied. Thus, theory and result in5] are extended. |

| Keywords: | drooping liquid film stability of heat transfer nonlinear surface tension |
