Sutherland's equation is a useful model for the temperature dependence of the viscosity of gases. I give a few details about it in this post: https://curiosityfluids.com/2019/02/15/sutherlands-law/ The law given by: $latex \mu=\mu_o\frac{T_o + C}{T+C}\left(\frac{T}{T_o}\right)^{3/2}&s=1$ It is also often simplified (as it is in OpenFOAM) to: $latex \mu=\frac{C_1 T^{3/2}}{T+C}=\frac{A_s T^{3/2}}{T+T_s}&s=1$ In order to use these equations, … Continue reading Solving for your own Sutherland Coefficients using Python
