Research Sampling

Boiling is a complex phase transition phenomenon. It involves complex fluid flows, various instability phenomena, and liquid-vapor phase change. We have developed a suite of novel theoretical and numerical methodologies for the study of boiling. The following figure shows a snapshot of the temperature field in a boiling simulation.
