The improved single-blow model includes the effects of axial conduction, heat flux into the tube wall, and Joule-Thomson expansion on the fluid temperature history at the exit of the test regenerator matrix. At the exit of the test regenerator, the variation with radius of the exit flow velocity was also investigated. In addition, the effects of oversize value and number of wire-screens on the thermal performance of the regenerator matrix are reported. © 1997 Elsevier Science Ltd. All rights reserved. |
