摘要
Molecular dynamics simulations have been carried out to investigate the collective transport properties of shear viscosity coefficients in the penetrable-sphere model fluid. A qualitative agreement is found between simulation results and an empirical Enskog-like approximation proposed in this present work. However, the mismatching tendencies are gradually growing with increasing both densities and repulsive energy parameters due to the cluster-forming structure and the phase transition from the fluid-like to the solid-like state. In addition, relevant historical background on viscosity is addressed to sketch the traditional kinetic theory of gases and simulation-based computational approaches.
