  1. Convection from laser-scanned ice roughness at multiple accretion vent times.

    McCarrell, Jaime Lynn, 1993-Baylor University.2017

    … study found that the commonly used realistic ice roughness models did not replicate the convective heat transfer results of one real ice roughness surface. The current study characterizes the convective heat transfer of four ice roughness surfaces exposed to accelerating flow similar to that …

  2. Droplet Rebound and Atomization Characteristics of Vibrating Surfaces

    Kendurkar, ChinmayVirginia Tech2023

    … due to accumulation of ice or snow on the wing surface due to impact with supercooled droplets when passing through clouds at high altitudes, causing loss of lift obtained by the wings. It was found that droplet impact characteristics are dependent on droplet size, surface roughness, surface …

  4. Micro-scale turbopump blade cavitation

    Pennathur, Sumita, 1978-Massachusetts Institute of Technology2001

    … The analysis suggests that residence time, surface roughness, surface tension, and passage area constraints are significant factors in cavitation inception and growth. A non-rotating microfabricated cascade has been designed, fabricated, and tested to quantify the behavior of micro-scale …
