Temperature profile (upper) and water concentration profile (bottom) along half of the simulation box for the water-methanol (average ) system at . Lines are obtained from a linear regression on the simulated data.
Time evolution of the heat flux density [defined in Eq. (9)] in the system water-methanol (average ) system at . Inner plot shows the initial transient period, characterized by fluctuations in the heat flux density. Time origin corresponds to the beginning of the application of the PeX algorithm. The steady state of is reached after .

Simulated thermodynamic states. All data at and except for water-methanol system at and . Experimental densities were taken from the following references: water-methanol (Ref. 64), water-ethanol (Ref. 61), water-DMSO (Ref. 65), water-acetone (Ref. 66). Thermal diffusion factor is a dimensionless quantity.
