Regenerative Heat Exchanger Theory
Regenerator theory deals with the physical equations defining the thermal and fluid flow fields that exist in a regenerator. These equations describe the temperature distributions in the matrix material and fluid as functions of both space and time and lead to a complex set of differential equations for which no closed-form solutions exist. In the following sections we explore the different types of regenerator designs commonly used in cryogenic devices and develop both the thermal and fluid dynamic equations that define their performance.
