Abstract : The purpose of the investigation was to determine the feasibility of using an analog computer to obtain the time derivative of the temperature response of a compact heat exchanger surface subjected to a step change in incoming fluid temperature; and to investigate the effect of the ratio of flow length to hydraulic diameter (L/D sub H) on the heat transfer and flow friction characteristics of compact heat exchanger surfaces. The method of maximum slope was used to determine the heat transfer information included. The results show that an analog computer can be a useful tool to aid in the collection and reduction of data. Results in the L/D sub H investigation were generally inconclusive and bear further investigation. (Author)
