Context and challenge: boiling heat transfer efficiency relies on a delicate balance between bubble generation near the surface and removal into the bulk, making reliable nucleation a prerequisite for robust performance across applications from power generation to electronics cooling and chemical processing.
Approach and objective: we show bubble nucleation is fundamentally collective: sites separated by the hydrodynamic-boundary-layer scale activate more readily and resist deactivation under changing thermal loads, consistent with a non-local hydrodynamic shielding mechanism, whereby neighboring bubbles slow the intervening flow, suppress convective heat removal, and stabilize vapor embryos.
If you plan to do a thesis or semester project on this:
What we expect: background in heat transfer, fluid mechanics, thermodynamics, and mechanical design. Hands-on experience with experiments/FEM modeling softwares will be a plus.
What you will learn: design of boiling setup; high-speed imaging; use and design of resistive temperature detectors; scientific communication through reports and presentation.
