This paper investigates the dynamic response of a heat exchanger having a sinusoidally time-dependent rate of internal heat generation. Results for both the transient-periodic and the steady-periodic, or frequency response, are given. These results include the response of the wall and fluid temperatures and the wall-fluid temperature difference. A phenomena of resonance in the amplitude ratio and phase shift is disclosed. Analytical results are obtained through the use of the Laplace transform technique. Experimental results are presented which compare favorably with the theoretical analysis. Heat exchangers to which these results apply include the heterogeneous nuclear reactor.
