Thermo-Capillary Driven Flow Under the Influence of Rotation and Magnetic Fields
… in space based processing. The control of this surface tension gradient driven flow is sought using (1) rotation and (2) magnetic field, and the effects of these are computationally studied in two separate parts. In the first part, the main parameters are the solutal Marangoni number Mc, …

Derivation of an Evolution Equation for Two-Dimensional Waves on Thin Films
… films subjected to gravity, fluid friction, surface tension, and Marangoni effects. The physical configuration is a thin liquid layer on a planar incline. Following previous studies, the Marangoni effect is incorporated by a constant surface tension gradient and yields a non-convex flux …

Partial Differential Equations of Thin Liquid Films: Analysis and Numerical Simulation
… for a film driven up an inclined planar solid surface by a thermally induced surface tension gradient. The range of effective contact slopes and parameter values are explained with the aid of Poincaré sections of the phase diagram of the third order ODE. In the second problem, we use theory …

Thermocapillary Convection During Laser Surface Heating (Surface Tension)
The fluid flow and the heat transfer during laser surface heating are studied. Surface tension gradient is identified as the dominant force from an order of magnitude consideration. Mathematical models for the thermocapillary convection within the molten pool are thus formulated. The models are …

Coupled Field Modeling of Gas Tungsten Arc Welding
… weld pool driving forces are included, namely surface tension gradient, plasma drag force, electromagnetic force, and buoyancy. The weld D/W predictions are validated with experimental results. They agree well. The effects of welding parameters (like welding speed, current, arc length, etc.) on …

On convection and stability of some welding and solidification processes
… which includes the Marangoni force on the free surface of a semi-infinite region of liquid steel when a point source of current and heat is incident on the free surface. An asymptotic solution to this problem is obtained in this thesis, and the surface tension gradient with respect to …
