Studies on heat transfer characteristics of vapor chamber under periodic-pulsed heat source
Advances in Mechanical Engineering, 2022 In a high-power microwave device, the intense electron beam causes a high-heat-flux on the collector’s inner surface which results in an instant temperature increase which eventually causes the output power to drop.

Feedback system for divertor impurity seeding based on real-time measurements of surface heat flux in the Alcator C-Mod tokamak [PDF]
, 2016 Mitigation of the intense heat flux to the divertor is one of the outstanding problems in fusion energy. One technique that has shown promise is impurity seeding, i.e., the injection of low-Z gaseous impurities (typically N2 or Ne) to radiate and ...

Investigation of heat flux intensity during composting of organic wastes
IOP Conference Series: Earth and Environmental Science, 2020 The authors present a three-dimensional model of organic agricultural waste, built on the basis of truncated cone. The movement of organic waste energy is modeled using a modified heat transfer equation, which includes volumetric heat capacity, chemical oxidation, and biological growth.
