Abstract

The theoretical part presents formulas for design calculations of conjugated unsteady heat transfer. Said formulas can find applications in the case of time arbitrary variations of heat release in tube wall at any time interval, at any tube section and with any combination of physical properties of tube materials and those of coolant within a wide zange of Re and Pr numbers.
In the experimental part the method used for investigation of unsteady heat transfer is considered. Comparison is made between our experimental and theoretical data for turbulent unsteady heat transfer to water in a steel tube.
