Numerical Methods for Evaluating Regenerator Performance

  • Robert A. Ackermann
Part of the The International Cryogenics Monograph Series book series (ICMS)


In Chapter 3, we presented the closed-form solution for the ideal regenerator equations. These solutions demonstrated the intuition and insight analysts used to describe regenerator performance and their ingenuity in solving the ideal regenerator equations without the use of digital computers. In this chapter we will review the techniques used to obtain solutions in the open form. The analytical models in the open form are based on finite difference techniques, in which the differential equations are replaced with difference equations and solutions are obtained by a stepwise iterative process. Open-form models are divided into several levels of complexity distinguished by the assumption employed.
