The Thiele hard sphere equation of state is an equation of state for a hard sphere fluid developed by Thiele in 1963 [1]. The equation provides a better approximation of the repulsive forces between molecules than the Van der Waals repulsive term. The equation is given below:

,

where:

is the compressibility factor of the hard sphere fluid;
is the pressure of the fluid;
is the molar volume of the fluid;
is the absolute temperature of the fluid;
is the gas constant; and
is the packing fraction of the fluid.

In terms of accuracy, the Thiele equation is superseded by the Carnahan-Starling equation of state
