Sneak Analysis Based on Energy Flow in Thermal Systems With Recirculation Structure

Sneak analysis in thermal systems means converting the thermal system into an electric system based on the similarity between them, and uses the mature sneak circuit analysis technology in the electric system to evaluate the overall safety of the thermal system. This paper presents a method of sneak...
