Abstract
Molecular Dynamics (MD) simulations are carried out to examine the effect of particle confinement on the pressure of 3D Yukawa gas. Confinement effects are taken into account by using perfectly reflecting boundary conditions in MD simulations. An equation of state relating pressure to number density is obtained. The results of the MD simulations show that in the weak coupling regime, pressure of confined Yukawa gas is much larger than the kinetic pressure and scales quadratically with number density. The results are compared with earlier theories and experiments which show quadratic scaling of dust pressure with density.
