Glycerol self-diffusion coefficients in glycerol-water-sodium chloride ternary solutions with different concentrations have been predicted using molecular dynamics simulation method. As glycerol concentration increases, glycerol self-diffusion coefficient decreases. Hydrogen bonds analysis has been made and it has been found that decreasing of glycerol self-diffusion coefficients is caused by decreasing of mean number of glycerol-water hydrogen bonds and increasing of mean number of glycerol-glycerol hydrogen bonds.

Key words: molecular dynamics simulation, self diffusion coefficients, glycerol
