The solution of the hypernettedhyphen;chain and Percusndash;Yevick approximations for fluids of hard spherocylinders

摘要

The hypernettedhyphen;chain (HNC) and Percusndash;Yevick (PY) approximations are solved numerically for isotropic fluids of hard spherocylinders with lengthhyphen;tohyphen;breadth ratios ranging from 2 to 6. The theoretical results are compared with the available Monte Carlo data for the equation of state and the pair correlation function. The HNC theory was found to predict the existence of a nematic phase at densities in reasonable agreement with recent computer simulations.
