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

Sutherland’s Law
When working on practical engineering applications, you often encounter problems where there are significant changes in temperature locally in the flow field. For instance, if you are doing a heat transfer calculation, you usually want to use the film properties (aka the properties adjacent to the wall). Doing this in any practical sense requires a … Continue reading Sutherland’s Law
