Viscosity variation with temperature for gases-
We would appreciate if some one gives us some formula for varation of viscosity for exhaust gases with temperature in the range of 300K to 600K other than Sutherlands formula.

Hi,
As an alternative to the Sutherland's law, check the power-law : http://www.grc.nasa.gov/WWW/cgns/sid...ViscosityModel Sincerely, the result will almost be the same, except that the power law should not be used for temperatures higher than 500K ... Anyway Sutherland's law might be more accurate ... Good luck Buch |

Use Lennard-Jones potentials. The difference is L-J takes into account the intermollecular forces, do not expcet much differnces in "normal" conditions.
