Journal ArticleDOI
The regenerative heat exchanger computer representation
TL;DR: In this article, the effect of thermal conductivity within heat storing material of the regenerator in a direction perpendicular to the direction of gas flow has been considered and the effect is discussed of the simplifying assumption that the problem can be regarded to be in two dimensions only.
Journal ArticleDOI
A robust method for regenerative heat exchanger calculations
A. Hill,A.J. Willmott +1 more
TL;DR: In this paper, a stable and accurate closed method for the solution of the differential equations describing thermal regenerator behavior is discussed, which employs the trapezoidal rule to provide accuracy and numerical stability.
Journal ArticleDOI
The effect of gas heat storage upon the performance of the thermal regenerator
A.J. Willmott,Clare Hinchcliffe +1 more
TL;DR: In this paper, a model of the regenerator in which a representation of gas carryover is attempted is presented, and the effect of the carryover predicted by this model is presented.
Journal ArticleDOI
Transient response of periodic-flow regenerators
A.J. Willmott,Alan Burns +1 more
TL;DR: In this paper, the responses of a thermal regenerator, initially at cyclic equilibrium, to permanent step changes in inlet gas temperature and in gas flow rate are presented in non-dimensional graphical form.
Journal ArticleDOI
Accurate and rapid thermal regenerator calculations
A. Hill,A.J. Willmott +1 more
TL;DR: In this article, the speed of calculation of the performance of thermal regenerators can be considerably increased using the method of Hill and Willmott (Int. J. Heat Mass Transfer30, 241-249 (1987)) which was developed from Razelos (Warme und Stoffubertr. 12, 59-71 (1979).
