Abstract The fluid variational free energy model is applied to calculate the equation of state (EOS) of the fluid (Ne/3,2He/3) mixtures at 296K. The pair potential is used to describe the He--Ne interaction. The calculated EOSs at 296K are compared with the experiments for solid Ne(He)₂. The validity of the potential and the calculated model is verified by comparison. The present model is extended to calculate the equation of state of the fluid He--Ne mixtures with different He:Ne compositions in the pressure 0--160GPa and temperature up to 10000K.
