Detailed Description

Huzel & Huang's combustion-gas viscosity fit, mu = 46.6e-10 M^0.5 T[R]^0.6, is in lbm/(in s).

It was converted with the lbf s/in^2 factor (6894.76) instead of 17.858, which made the gas
viscosity g_c = 386x too high and the Bartz convective coefficient ~117x too low -- the
long-standing "ablative convection ~283x low". Checked against NASA CEA transport properties,
not against the code.
