Abstract
ABSTRACT This work uses elementary theoretical arguments to estimate whether softening of the surface could be used, along with surface texture and chemistry, to control superheat required for onset of nucleate boiling. For an ideal, smooth surface a mild decrease of the required superheat is predicted. In turn, an approximate closed-form model of vapor trapping and bubble seeding from soft surface with conical cavities shows linear dependence between the required superheat and the substrate’s shear modulus. Based on these results, considerations involved in implementing soft coatings for boiling applications and relevant outstanding fundamental questions are also briefly discussed.
期刊介绍：
Nanoscale and Microscale Thermophysical Engineering is a journal covering the basic science and engineering of nanoscale and microscale energy and mass transport, conversion, and storage processes. In addition, the journal addresses the uses of these principles for device and system applications in the fields of energy, environment, information, medicine, and transportation.
The journal publishes both original research articles and reviews of historical accounts, latest progresses, and future directions in this rapidly advancing field. Papers deal with such topics as:
transport and interactions of electrons, phonons, photons, and spins in solids,
interfacial energy transport and phase change processes,
microscale and nanoscale fluid and mass transport and chemical reaction,
molecular-level energy transport, storage, conversion, reaction, and phase transition,
near field thermal radiation and plasmonic effects,
ultrafast and high spatial resolution measurements,
multi length and time scale modeling and computations,
processing of nanostructured materials, including composites,
micro and nanoscale manufacturing,
energy conversion and storage devices and systems,
thermal management devices and systems,
microfluidic and nanofluidic devices and systems,
molecular analysis devices and systems.
