“…Thus, we considered a problem of electron transpiration cooling of the surface, heated by a laser. We solved the transient heat conduction equation (12) in cylindrical coordinates, using the finite difference method with the second-order central scheme for the conductive term and the forward Euler explicit scheme to advance in time. The time step for the problem was chosen ∆t = 1 × 10 −4 to satisfy the Courant-Friedrichs-Lewy condition.…”

“…During the 1910s, the cooling effect was first observed by measuring a change of resistance of a heated filament when the thermionic current was cycled on and off [12][13][14]. The thermionic cooling effect has been known and taken into account in the energy balance of various applications involving thermionic emission (e.g.…”
