Temperature prediction for components of a cogeneration system based on measurement of heat flux on heat sources

Abstract

A cogeneration system (CGS) powered by an internal combustion engine is generally enclosed with panels to improve thermal efficiency and reduce noise. On the other hand, there are upper temperature limits to maintain reliability of components in the CGS. Therefore, temperature prediction is important to design of the CGS. In this study, a thermal resistance model of the CGS has been considered for simplification of the prediction. Heating value of the heat sources has been defined by calculating heat flow through the thermal resistances which have been easily estimated by measurement of heat flux. The thermal resistance model based on heat flux measurement has been verified experimentally.
