Abstract

"The object of this investigation is to study the mutual dependence of heat and mass transport in laminar and hydrodynamically developed tube flow. Consideration is given to gas flow through a tube whose wall is coated with a sublimable materials so that heat and mass transfers take place between the wall and the flowing gas stream. The tube wall is thermally insulated from the external environment, with the result that the latent heat required by the sublimation process at the wall is supplied solely by convective transfer from the gas. The analysis of the problem requires simultaneous solution of the energy and diffusion equations with couplings provided by the boundary conditions. An analytical solution is facilitated by employing a linear saturation state relationship for the vapor of the subliming solid. the resulting eigenvalue problem does not belong to the conventional Sturm-Liouville system. A special integral relation is derived which serves as an orthogonality condition. Mathematical expressions are derived and numerical results are presented for the streamwise variations of the bulk temperature and bulk mass fraction, of the wall temperature and mass fraction, of the wall heat and mass transfer rates, and of the local Nusselt number for nine different cases. Representative temperature and mass fraction profiles are also presented. Entrance lengths which characterize the near approach to fully developed conditions are tabulated. comparisons of typical results are made with the case of coupled transport in a parallel-plate channel"--Abstract, page vii-viii.
