Local H theorem for Enskog and Enskog-Vlasov equations with a modified Enskog factor
Aoto Takahashi, Shigeru Takata
The local H theorem is shown to hold for the Enskog equation with a modified Enskog factor proposed by the authors [Phys. Rev. E 111, 065108 (2025)]. This is a stronger statement t…
Numerical analysis of the thermal relaxation of the dense gas between two parallel plates: the free energy monotonicity for the Enskog equation
Shigeru Takata, Soma Sakata, Aoto Takahashi +1
The thermal relaxation problem between two parallel plates with the same temperature is investigated, aiming to study the behavior of the free energy of the dense gas described by…
Fluid-dynamic limit of the Enskog equation with the guaranteed H-theorem
Aoto Takahashi, Shigeru Takata
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 b…
Enskog and Enskog-Vlasov equations with a slightly modified correlation factor and their H theorem
Shigeru Takata, Aoto Takahashi
A novel modification of the original Enskog equation is proposed. The modification is much simpler than that is made in the modified (or revised) Enskog equation proposed by van Be…
