In the present paper, a new equation for the dynamic viscosity of propane is presented, which is suitable for the application in mixture models. The dilute-gas contribution was adopted from Vogel and Herrmann (J Phys Chem Ref Data 45:043103, 2016). The residual part is an empirical approach designed following the example of thermodynamic Helmholtz equations of state. With this functional form, an approach is proposed, which will allow to combine pure-fluid equations in the manner of high precision Helmholtz equations of state in a multifluid mixture model in the future. The parameters of the equation are adjusted to experimental data, so that the data are mostly reproduced within their experimental uncertainty. The present equation is valid in a temperature range from 90 K to 525 K with a maximum pressure of 145 MPa. [ABSTRACT FROM AUTHOR] |
