Abstract:

Results of an analytic study of heat transfer problems associated with storage of high temperature gases are presented. It contains analytic discussions of the basic concepts of radiant heat transfer, conductive heat transfer, and chemical boundary layers. Analytic expressions for characteristic radiation lengths, characteristic radiative cooling rates, and characteristic conductive cooling times are developed and evaluated in a numerical study of hydrogen, helium, argon, and air. Numerical studies clearly demonstrate the fact that practical storage of high temperature gases will be limited to temperatures below the onset of the important bound-free radiation processes. In hydrogen this temperature limit is very low 2,600 Kelvin due to the formation of the negative ion H-. In the case of helium, the limiting temperature is unusually high 8,300 Kelvin as a consequence of the high ionization potential. The influence of heterogeneous chemical reactions is limited to a thin chemical boundary layer which can be ignored in analytic studies of the temperatur profiles. Author
