Abstract

Abstract: The paper investigates the performance of the ball packed-bed regenerator from the study of inertial, viscous resistance and thermal characteristics of the packed bed regenerator. In the first part of the paper the inertial resistance and viscous resistance characteristics of the regenerator based on previous experimental data are studied. The Ergun's equation has been accepted widely to calculate the pressure drop in the thermal regenerator with its two coefficients, 150 and 1.75. Revised Ergun's equation is achieved for ball packed regenerator. The values of coefficients of Ergun's equation calculated by simulation are compared with the experimental results. In the second part of the paper the thermal characteristics of the regenerator are studied by using 3-D transient model. The variation of pressure drop, temperature, effectiveness, velocity along the regenerator bed is studied and presented.
