Theoretical Scheme for Thermal Conductivity of Non-Spherical Molecular Fluids

Satyendra Prasad Singh, Madan Kumar Choudhary, Mukesh Kumar Sinha and Tarun Kumar Dey

Thermal conductivity of molecular fluids of non-spherical molecules interacting via the Gaussian overlap with constant energy (GOCE) potential are studied using a perturbation theory. The thermal conductivity λ of the molecular fluid are expressed in terms of the hard sphere (HS) fluid of properly chosen hard sphere diameter. The thermal conductivity λ of a dense HS fluid are obtained by the Revised Enskog theory (RET). Theory is applied to estimate λ of fluid N2. The agreement is good at low density limit.
