Advanced Versions of Heat Pumps With Zeotropic Refrigerant Mixtures

January 1, 1986
Author(s)
R Radermacher
Two heat pump cycles operating with halogenated hydrocarbon mixtures are considered. Each Coefficient of Performance (COP) increases up to 50% under extreme temperature lifts when reciprocating compressors are employed. This is due to a reduction of the

Numerical Characterization Of The Discharge Coefficient In Critical Nozzles

July 1, 1998
Author(s)
Aaron N. Johnson, Pedro I. Espina, John D. Wright, G E. Mattingly, C L. Merkle
The discharge coefficient in critical nozzles flowing N 2, Ar, CO 2, and H 2 in the Reynolds Number range (2,000 to 22,000) is studied computationally to assess the capability of Computational Fluid Dynamics (CFD) in assisting experimental calibration. A
