A finite difference/front tracking method for direct simulations of multiphase flows is described. A few examples of both two- and three-dimensional simulations are presented. Background Multi-phase flows are central to many industrial processes. Heat transfer by boiling is the preferred mode in most power plants and bubble driven circulation systems are used in metal processing operations such as steal making, ladle metallurgy and the secondary refining of aluminum and copper. In combustion of liquids the fuel is usually introduced as a spray, and sprays are central to most painting and coating processes. Similarly, many natural processes involve bubbles and drops. Rain is perhaps the most common example, but bubbles also play a major role in the air/ocean interaction, for example.
