sutherland temperature computingHi,
May I ask how to compute sutherland temperature? Shall I always use 110 K? Thank you very much. |

In my solver for air properties I use:
mu = C1*pow(T, 3/2)/(T+C2) k = C3*pow(T, 3/2)/(T+C4) where; 1.458e-06 !C1 - Sutherland's Law Dynamic Viscosity Constant 110.4 !C2 - Sutherland's Law Dynamic Viscosity Constant 2.495e-03 !C3 - Sutherland's Law Thermal Conductivity Constant 194.0 !C4 - Sutherland's Law Thermal Conductivity Constant I am also curious if there are better values to be using based on the temperature ranges I am simulating... :) |
