Viscosity of pure carbon dioxide at supercritical region: Measurement and correlation approach

▶ Proposing a new correlation without need to complicated calculations for predicting the viscosity of CO2 in the critical region. ▶ The simplicity of correlation is quite demanding for some modeling work with complicated process of solving mathematical equations such as Computational Fluid Dynamics (CFD) technique. ▶ Low prediction error in range of studied temperature and pressure. ▶ Comparison of prediction error by the presented correlation and some available correlations in the literature confirms the superiority of this work.
