Analysis of the transient and steady-state heat transfer in rotary regenerative heat exchanger
Abstract
The theoretical analysis and calculation of the transient and periodic steady-state temperature distribution of the rotor material and fluids in a rotary regenerator are reported. The transient temperature distribution of the fluids is also measured in a test regenerator, and the results obtained by the numerical method agree with those of the experimental measurement. The effect of the conduction of the rotor material on the temperature distribution is also evaluated. The mathematic model presented in this paper provides a theoretical basis for the optimum design of the regenerator.
