摘要

This paper presents a new method to simulate heat transfer across the interface separating immiscible liquids. One-field volume tracking is used which involves solving one set of equations for conservation of mass, momentum and energy. The original idea behind volume tracking methods has been used not only to advect mass and momentum but also energy across cell boundaries. Moreover, the Van Leer method is used to approximate advection temperatures across the sharp temperature gradients existing at fluid-fluid interface. As an example, the fall of a hot liquid droplet in a cool surrounding is simulated. The effect of changing the surrounding thermal diffusivity is studied. Results show a region of high temperature in the wake region behind the droplet and a temperature distribution along the droplet surface with the maximum temperature at 120° after the attack angle.
