Pool Boiling

Boiling heat transfer has many applications, such as electronics cooling, battery thermal management, thermal power generation, nuclear reactor vessel cooling, etc. High heat transfer coefficients can be achieved through pool boiling because of its ability to capitalize on latent heat transport. Pool boiling is one of the fundamental phenomena that occur in a flat thermosyphon. Therefore, fundamental studies on pool boiling over various surfaces are needed to get insights into the performance enhancement of a flat thermosyphon. Pool boiling experiments are being conducted on various mini-channelled surfaces to get insights into the bubble dynamics and heat transfer enhancement. High-speed imaging is being used to study the bubble dynamics, and Infrared thermography is being explored to study the spatial variation of temperature and heat flux. The in-house pool boiling experimental setup is shown in the figure.
