| Abstract | The fluid-dynamic limit of the Enskog equation with a slight modification is discussed on the basis of the Chapman–Enskog method. This modified version of the Enskog equation has been recently shown by the present authors to ensure the H-theorem. In the present paper, it is shown that the modified version recovers the same fluid-dynamic description of the dense gas as the original Enskog equation, at least up to the level of the Navier–Stokes–Fourier set of equations inclusive. Since the original Enskog equation is known to recover the fluid-dynamical transport properties well, this result implies that the modified version of the Enskog equation provides consistent descriptions both thermodynamically and fluid-dynamically. |
