On thermal conductivity and viscosity of gaseous alternative refrigerants at atmospheric pressure
A combination of strongly theoretical approaches and heuristic scenarios to the calculation of transport coefficients of dilute gases is presented. It is shown that the fundamental theoretical models do not contain adjustable parameters and allows the description of transport properties of pure HCFCand HFC refrigerants, and their mixtures including polar fluids. The validity of this scheme was confirmed by comparison of calculated results to experimental values made for sixth pure refrigerants, two ternary and one binary mixtures (R32, R123, R124, RI25, R134a, Rl43a, R404A, R407C and R410A). Agreement of the present values with those of some experimental results are quite satisfactory.
