Transport and equilibrium properties of the CO2 + n-butane mixture based on molecular simulation data dataset

  • 1. EDMO icon Technical University of Berlin

Description

This dataset contains molecular simulation data supporting a generalized simulation-based framework for predicting
thermodynamic equilibrium and transport properties of pure CO2, pure n-butane, and their binary mixture. Fundamental Helmholtz energy equations of state (EOS) are constructed from extensive molecular simulation data on
residual Helmholtz energy derivatives, using ideal-gas contributions taken from reference EOS. Shear viscosity and thermal conductivity are predicted via residual entropy scaling correlations coupled with the
simulation-based Helmholtz EOS. All transport-property data needed for parameterization, including dilute-gas limits,
are sampled exclusively by molecular dynamics simulation.

The dataset is organized into two main parts:
1) EOS data: residual Helmholtz energy derivatives (eos_co2_butane_tables.zip)
2) Transport-property simulations  (transport_co2_butane.zip)
