Heat capacity of liquid Al: Molecular dynamics simulations

Abstract

The heat capacities at constant pressure, ${c}_{P}$, at constant volume and at fixed volume, and the isothermal bulk modulus, are calculated for liquid Al over a wide range of temperatures using molecular dynamics simulations with interactions due to Ercolessi and Adams and Mei and Davenport. ${c}_{P}$ has only a weak temperature dependence, with a shallow minimum that results from the opposing effects of a gradual loss of shear resistance and thermal expansion.
