RISA Possible Role of Nanostructured Ridges on Boiling Heat Transfer Enhancement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Evaporation of a nanoscale meniscus on a nanostructured heater surface is simulated using molecular dynamics. The nanostructures, evenly spaced on the surface, are ridges with a width and height of 0.55 nm and 0.96 nm, ...
Fundamental Roles of Nonevaporating Film and Ultrahigh Heat Flux Associated With Nanoscale Meniscus Evaporation in Nucleate Boiling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The threephase moving contact line present at the base of a bubble in nucleate boiling has been a widely researched topic over the past few decades. It has been traditionally divided into three regions: nonevaporating film ...
Numerical Simulation of Forced Convective Boiling in a Microchannel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Forced convective flow boiling in a single microchannel with different channel heights was studied through a numerical simulation method to investigate bubble dynamics, two-phase flow patterns, and boiling heat transfer. ...
An Experimental Study on Cryogenic Spray Quenching of a Circular Metal Disk, Part I: Effects of Mass Flux, Spray Fluid Inlet Subcooling, and Gravity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This is the first part of a two-paper series that reports the design, experimentation, and results of a spray quenching experiment of a circular metal disk in terrestrial gravity condition. The objective of this experiment ...
An Experimental Study on Cryogenic Spray Quenching of a Circular Metal Disk II—Chilldown Efficiency and Effects of Coating and Flow Pulsing
Publisher: The American Society of Mechanical Engineers (ASME)
