A PREDICTIVE EXTENDED CORRESPONDING STATES MODEL FOR PURE AND MIXED REFRIGERANTS.

Author(s) : ELY J. F., HUBER M. L.

Summary

THE AUTHORS HAVE DEVELOPED A PREDICTIVE CORRESPONDING STATES MODEL FOR THE THERMOPHYSICAL PROPERTIES OF REFRIGERANTS. DENSITY, ENTHALPY AND ENTROPY ARE PREDICTED USING THE PRINCIPLE OF EXTENDED CORRESPONDING STATES. THIS MODEL USED SHAPE FACTORS TO INSURE CONFORMALITY AMONG THE VARIOUS COMPONENTS AND R134A IS USED AS THE REFERENCE FLUID. A ONE-FLUID CORRESPONDING STATES MODEL IS USED TO PREDICT THE VISCOSITY AND THERMAL CONDUCTIVITY. CALCULATIONS MAY BE PERFORMED ON PURE FLUIDS OR ON MIXTURES OF UP TO 20 COMPONENTS. A BUILT-IN DATABASE CONTAINS MANY COMMON REFRIGERANTS INCLUDING R11, R114, R12 AND R13, AS WELL AS R123, R134A AND OTHERS. THE PROGRAM CAN < LEARN > NEW COMPONENTS USING ONLY A MINIMUM AMOUNT OF INFORMATION (MOLECULAR WEIGHT, NORMAL BOILING POINT AND THE CRITICAL PARAMETERS).
