摘要：

We present a new wide-ranging correlation for the viscosity of krypton based on critically evaluated experimental data. For the first time, such a correlation has as its basis the entropy scaling approach. We base the residual contribution on the Lennard-Jones fluid, resulting in one adjustable parameter for the entire phase diagram away from the dilute-gas limit. The estimated uncertainty is less than 2.0 % (at the 95 % confidence level) over the entire phase diagram, except in the extended critical region. The correlation is valid from 70 K to 5000 K for the dilute gas, and from 115.775 K to 750 K in the fluid phase, with a pressure limit equal to that of the melting curve
