  • The isoenthalpic-isobaric ensemble (constant enthalpy and constant pressure ensemble) is a statistical mechanical ensemble that maintains constant enthalpy and constant pressure applied. It is also called the -ensemble, where the number of particles is also kept as a constant. It was developed by physicist H. C. Andersen in 1980. The ensemble adds another degree of freedom, which represents the variable volume of a system to which the coordinates of all particles are relative. The volume becomes a dynamical variable with potential energy and kinetic energy given by . The enthalpy is a conserved quantity.Using isoenthalpic-isobaric ensemble of Lennard-Jones fluid, it was shown that the Joule–Thomson coefficient and inversion curve can be computed directly from a single molecular dynamics simulation. A complete vapor-compression refrigeration cycle and a vapor–liquid coexistence curve, as well as a reasonable estimate of the supercritical point can be also simulated from this approach.NPH simulation can be carried out using GROMACS and LAMMPS.

  • 等エンタルピー定圧集団(とうエンタルピーていあつしゅうだん、英: Isoenthalpic-isobaric ensemble)は、一定のエンタルピーと印加される一定の圧力を保つ統計力学的集団(アンサンブル)である。粒子の数も一定に保たれ、アンサンブルとも呼ばれる。1980年に物理学者のH. C. Andersenによって発表された。このアンサンブルは全ての粒子の座標が関係のある系の可変容積を表わすもう一つの自由度を加える。容積はによって与えられるポテンシャルエネルギーと運動エネルギーの変数となる。エンタルピーは保存量である。 (ja)
