The physical and mathematical models of thermocapillary-buoyancy convection in two immiscible liquid layers are established. In order to capture the free surface and the liquid-liquid interface deformation, Runge-Kutta method is adopted to solve the Young-Laplace equation. Numerical simulation of thermocapillary-buoyancy convection in encapsulated liquid bridge is performed by employing primitive valuable method and finite volume method. The fluids of liquid bridge and liquid encapsulation are FC-70 and KF-96, respectively. Furthermore, the profiles of temperature and velocity in encapsulated liquid bridge are obtained. Meanwhile, the effects of a series of non-dimensional parameters on the thermocapillary-buoyancy convection are analyzed.
