Classes
struct	GasTransportUtils::LennardJonesParameters
	Parameters of the Lennard-Jones (12-6) potential of a species. More...

Namespaces
namespace	GasTransportUtils
	Transport properties of dilute gases: Lennard-Jones parameters of the NASA 7-coefficient species, collision integrals, Chapman-Enskog viscosity and binary diffusion coefficients, the modified Eucken thermal conductivity, and the low-density viscosity and thermal conductivity of steam.

Functions
