Article Preview

An analysis has been made for the flow and regeneration characteristics in screen mesh and parallel wire regenerators. A model is put forward by taking the matrix as an anisotropic porous medium. The regeneration characteristics are investigated by comparing the Nu, hsf and NTU between the both regenerators under oscillating flow conditions. It is indicate that the heat transfer performance in screen mesh regenerator is better than the one in parallel wire regenerator at the same oscillating flow condition. The mass flow distribution homogeneity factor Fm is conceived and derived to reflect the gas flow distribution in the porous matrix, and heat penetration depth δt and porosity are also indicated to be the indexes of optimizing the matrix geometry.
