Energetics and limitations of passive electron transpiration cooling for hypersonic leading edges
Bryce Boyer, Timothy S. Fisher
Electron transpiration cooling (ETC) offers a promising approach for thermal management of hypersonic vehicles by leveraging thermionic emission from the leading edge. While emitte…
Thermal Conductance Correlations of Static Lubricated Ball Bearings
Indronil Ghosh, John P. McHale, Yoshimi R. Takeuchi +3
Ball bearings are commonly used to reduce the friction in rotating mechanical components. The present work reports improved numerical approaches to model bearing thermal conductanc…
Numerical Model of Thermionic- and Photo- emission Electron Heat Spreading
Indronil Ghosh, Timothy S. Fisher
Thermionic emission has been exploited to give rise to the theory of thermionic cooling also known as electron transpiration cooling, which can potentially serve as a powerful and…
New Plasma Sheath Potential Solutions in Cylindrical and Spherical Coordinates
Indronil Ghosh, Timothy S. Fisher
Leading edges of hypersonic vehicles can reach temperatures greater than 2000 °C, and radii of curvature smaller than 1 cm, at which thermionic emission (also known as electron tra…
