A generalized model for viscosity and thermal conductivity of trifluoromethane (R23).

Author(s) : SHAN Z., PENONCELLO S. G., JACOBSEN R. T.

Summary

A model for the calculation of the viscosity and thermal conductivity of R23, expressed in terms of temperature and density, is presented. The model is based on Eyring's theory of significant liquid structure. The same functional form was used to represent the viscosity and thermal conductivity. The constants for each model were determined by correlating selected experimental data. The model-calculated values for R23 agree very well with the literature data for viscosity at temperatures from 153 to 570 K and for thermal conductivity at 170 to 433 K at pressures up to 60 MPa.
