The liquid-vapour phase change in porous media plays a vital role in a wide variety of engineering applications. Although significant progress has been made in the past, some elements of phase-change phenomena are not well understood despite many years of extensive research. One of the areas where there is currently a need for further research is liquid-vapour interface instabilities of the capillary-driven flows. The interface instabilities can lead to performance anomalies and mechanical damage of heat transfer equipment by altering the phase-change process. The proposed research project aims to study thermo-hydraulic instabilities encountered during the liquid-vapour phase change process in porous media through experimental and numerical investigation. One of the main goals of the project is to expand a previously developed mathematical model to be able to suggest design improvements to eliminate or remedy the performance anomalies.
