NONIDEAL REGENERATOR PERFORMANCE. THE EFFECT OF VOID VOLUME FLUID HEAT CAPACITY.

Author(s) : DANEY D. E., RADEBAUGH R.

Summary

THE PERFORMANCE OF LOW TEMPERATURE REGENERATORS ARE STUDIED FOR A RANGE OF PARAMETERS SPECIALLY INTERESTING FOR CRYOCOOLING. WITH A ONE-DIMENSIONAL MODEL OF THE FLOW OF AN INCOMPRESSIBLE FLUID DEPENDING ON TIME, THE AUTHORS SHOW THAT THE HEAT CAPACITY OF THE FLUID IN THE VOID VOLUME MAY HAVE A STRONG EFFECT ON THE BEHAVIOUR OF THE REGENERATOR. TAKING INTO ACCOUNT THE VOID VOLUME TERM MARKEDLY IMPROVES THE PREDICTION OF EFFICIENCY WHEN THE HEAT CAPACITIES OF THE VOID VOLUME AND OF SOLIDS ARE SIMILAR. FOR SOME LOW THERMAL LOADS, AN INCREASE IN THE HEAT CAPACITY OF SOLIDS MAY ACTUALLY REDUCE EFFICIENCY.
