This paper, based on the Fermi gasmodel, studies the energy of free electron gas in metal, discusses the highest energy, the average energy and the energy level density of free electrongas.
A model of mass transfer coefficients in liquid phase near freegas-liquid interface is developed based on the energy spectrum functions of isotropic turbulence.
The model for the escape of rising gas bubbles at free surfaces, which is a part of the drift-flux model, has been improved to include a rate for their escape.
