Instabilities of Thin Viscous Liquid Film Flowing down a Uniformly Heated Inclined Plane
Instabilities of a thin viscous film flowing down a uniformly heated plane are investigated in this study. The heating generates a surface tension gradient that induces thermocapillary stresses on the free surface. Thus, the film is not only influenced by gravity and mean surface tension but also the thermocapillary force is acting on the free surface. Moreover, the heat transfer at the free su...
متن کاملInfluences of Interfacial Shear in Turbulent Film Boiling on a Horizontal Tube with External Flowing Liquid
The paper presents a theoretical study about turbulent film boiling on a horizontal tube with external flowing liquid. The high velocity flowing liquid is determined by potential flow theory. By using Colburn analogy, the present paper successfully addresses a new model to predict the vaporliquid interfacial shear, applies the interfacial shear into the forced balance equation and then combines...
متن کاملHeat Transfer Efficiency of Turbulent Film Boiling on a Horizontal Elliptical Tube with External Flowing Liquid
Film boiling on a horizontal elliptical tube immersed in external flowing nitrogen liquid is investigated in the present paper. The isothermal wall temperature is high enough to induce turbulent film boiling, and then a continuous vapor film runs upward over the surface. The high velocity of the flowing saturated liquid at the boundary layer is determined by potential flow theory. In addition, ...
متن کاملMarangoni instability of a thin liquid film resting on a locally heated horizontal wall.
Long-wave Marangoni instabilities can be induced thermally on a thin liquid layer overlying a horizontal solid substrate with either a uniform or a nonuniform base temperature. For a nonuniform base temperature, the film height thickens near the region where temperature gradients are negligible and severely thins upstream; "fingering" patterns are observed in this region. These states are relat...
