Computation for Surface Tension of Molecular Fluids

Author(s): Madan Kumar Choudhary, Manoj Kumar and Tarun Kumar Dey

The effective pair potential for molecular fluid of molecules possessing tetrahedral symmetry is expressed in the effective Lennard-Jones (ELJ) (12 - 6) potential form in terms of effective diameter σT and well depth ∈T. We employ the effective diameter hard sphere theory (EDHST) for the ELJ (12-6) fluid in terms of the hard sphere fluid of properly chosen hard sphere diameter. We employ this theory to estimate surface tension γ of CCl4. In all these cases, the agreement is fairly good.
