Transient Response of Heat Exchangers with One Infinite Capacitance Fluid
TL;DR: In this paper, a transient response analysis for a heat exchanger with an infinite capacitance fluid on the shell side is presented, and the results cover all practical combinations of the dependent parameters and are presented as a set of charts.
Abstract: Information on the transient response of heat exchangers is essential to produce the optimum heat exchanger operation for the required function. A transient response analysis is presented for a heat exchanger with an infinite capacitance fluid on the shell side. The inlet temperature of the finite capacity fluid is stepped, and the heat exchanger response is represented by the change in the temperature of this fluid at the outlet of the tubes. The results cover all practical combinations of the dependent parameters and are presented as a set of charts. Results of previous workers in this field are discussed. Their charts cover a very restricted range of heat transfer conditions and are therefore of limited use. In addition, assumptions have been incorporated into their analyses which result in major discrepancies.

TL;DR: The third edition of the second edition as discussed by the authors was published in 1964 and contains basic test data for eleven new surface configurations, including some of the very compact ceramic matrices, in both the English and the Systeme International (SI) system of units.
Abstract: This third edition is an update of the second edition published in 1964. New data and more modern theoretical solutions for flow in the simple geometries are included, although this edition does not differ radically from the second edition. It contains basic test data for eleven new surface configurations, including some of the very compact ceramic matrices. Al dimensions are given in both the English and the Systeme International (SI) system of units.

TL;DR: In this paper, the transient response of heat exchangers is investigated and analog solutions are used to supplement some limiting analytical solutions to provide fairly complete coverage for the heat exchanger encountered in gas turbine plants.
Abstract: Transient response of heat exchangers are investigated. Analog solutions are used to supplement some limiting analytical solutions to provide fairly complete coverage for the heat exchangers encountered in gas turbine plants. Because a gas-flow exists on at least one side of the heat transfer surface, these exchangers are characterized by a large wall capacitance effect. Where greater generality is possible the extension to other heat exchangers is indicated. Included is a consideration of the transient response of insulated ducts and pipes, applicable to either the flow of liquids or gases. (auth)
