The deployment of wind energy is constrained by wind uncontrollability, which poses operational problems on the electricity supply system at high penetration levels, lessening the value of wind-generated electricity to a significant extent. This paper studies the viability of hydrogen production...

One of the most common problems arising from the application of life cycle assessment is the allocation of environmental loads in processes yielding several useful products. This is the case for cogeneration plants, and in general, for any energy plant producing more than one useful energy flow....

The one-particle distribution for the modulus of the velocity of a hard-disk fluid inside a small circular cavity is studied. Due to the geometry of the cavity, the total angular momentum L is conserved if the (elastic) particle–wall collisions are specular, leading to a new, special...

A simple approximate expression is proposed for the energy dependence of the microcanonical density of states of a classical hard-particle fluid column of infinite height in a uniform gravitational field. This expression is based on the exact result in one dimension and depends on an effective...

The microcanonical molecular dynamics ensemble describes a system with a fixed number of particles in a given volume and with constant total energy and total linear momentum. The primary phase integrals of this ensemble for a hard-core fluid are derived by using geometrical arguments. The...

The use of periodic boundary conditions in molecular-dynamics simulations leads to the microcanonical EVNMG ensemble of Ray and Zhang [J.R. Ray, H. Zhang, Phys. Rev. E 59 (1999) 4781] in which the total linear momentum M and the generator of infinitesimal Galilean boosts G are conserved...
