Heat transfer in a rarefied polyatomic gas I. Plane parallel plates (Q1064233)

The \textit{F. B. Hanson - T. F. Morse} model for a polyatomic gas [Phys. Fluids 10, 345 ff. (1967)] is used to investigate heat transfer between two plane parallel plates. The boundary value problem is transformed into a system of integral equations which is then solved numerically. The dependence of heat transfer, temperature and density profiles on Knudsen number, internal energy, Eucken factor and collision relaxation number is studied. Results are compared with the available experimental data on nitrogen and some previously reported variational results on heat transfer [\textit{S. K. Hsu} and \textit{T. F. Morse}, ibid. 15, 584-591 (1972; Zbl 0242.76045)].
