Study on Dynamic Heat Measurement Method afterStep Change of System's Flux

Abstract

The flow and conduction characteristic of fluid in radiator after step change of flux is analyzed. The "level-move" presumption of temperature distribution curve in radiator during transient is put forward. On the basis of the presumption, the function relationship of heat quantity of radiator and time during transient is deduced, and the validity of the function relationship is proved through experimentation. These conclusions offered the valuable reference for the moving characteristic research of the new heating measurement and control system.
