Influencing contact-line behavior in dynamic wetting through thermocapillarity and surface topography
Dynamic wetting involves an advancing fluid displacing a receding fluid on a solid surface. This phenomenon can be seen in day-to-day occurrences such as water droplets sliding on a glass window on a rainy day, where the droplet displaces the air surrounding the glass surface as it slides, and in …

Interfacial Dynamics and Applications in Optofluidics
… such as radiation pressure, light scattering, thermocapillarity, Kerr nonlinearity, and thermal effect. However, such nonlinear effects have yet to be thoroughly investigated and compared in the literature. In this study, we first investigate a micron-sized liquid spherical resonator and …

Melt motion in floating-zone process for single crystal growth with an axial magnetic field
… force, crystal growth speed, buoyancy, thermocapillarity and electromagnetic body force are the driving forces involved in the floating-zone process for growing single crystal. The strong, DC magnetic field eliminates the inertial effect of the melt motion and confines the viscous effect …

Investigation of Thermocapillary Flows Around Hemispherical Bubbles
… High order buoyancy effects tend to cancel thermocapillarity for downward facing bubbles. Natural convection is the dominant mechanism for an upward facing bubble. Thermocapillary flows could be significant in situations where either moderate size stable bubbles at present or high heat …

A moving mesh method for non-isothermal multiphase flows
In this thesis, a numerical method is developed for simulating non-isothermal multiphase flows, which are important in many technical applications such as crystal growth and welding. The method is based on the arbitrary Lagrangian Eulerian method of Li (2013). The interface is represented …

Buoyancy-thermocapillary convection of volatile fluids in confined and sealed geometries
Convection in a layer of fluid with a free surface due to a combination of thermocapillary stresses and buoyancy is a classic problem of fluid mechanics. It has attracted increasing attentions recently due to its relevance for two-phase cooling. Many of the modern thermal management technologies …
