Renormalization Group Theory for Fluids to Greater Density Distances from the Critical Point

摘要: A recently developed renormalization group (RG) theory for fluids begins with an expression the free energy repulsive interactions only, then employs RG procedure to take into account contributions that come from fluctuations of all wavelengths in presence attractive inter-molecular limited range. The has had some success describing volumetric properties real at critical point and out distances within approximately ±50% density. In calculations, density dependence radial distribution function was ignored. now been modified account. Predictions as thus amended are compared measurements made argon near temperature densities zero more than twice
