From Nanochannels to Oscillating Heat Pipes: Understanding and Engineering Liquid-Vapor Interfaces for Passive Thermal Management

Speaker: <a href="https://maroo.syr.edu">Prof. Shalabh C. Maroo, Syracuse University</a> <strong>Abstract</strong><br> Thermal management of high-power electronics increasingly hinges on how we understand and engineer liquid-vapor interfaces, from the molecular scale to the device scale. This talk presents an experimental and computational body of work spanning three connected threads. First, I will show how the disjoining pressure of water, a near-surface molecular interaction, can be quantified from wicking experiments in silicon-dioxide nanochannels, reaching pressures as high as ~1.5 MPa. Implemented in continuum CFD, this relation predicts bubble nucleation temperatures that
