Heat Transfer in Absorbing and Emitting Media (Gaseous Radiation)

  • Rajendra KarwaEmail author


The radiation exchange between an absorbing and emitting gas and a solid surface is considerably more complex than exchanges between solid surfaces through transparent medium. The specific features of the gaseous radiation have been discussed in this chapter. The procedure for the calculation of net heat exchange, presented by Hottel, between a black enclosure and isothermal (uniform temperature) gas volume consisting of CO2 and/or water vapour is given in Sect. 12.3 followed by a simplified treatment of gray enclosure. In the end, a brief introduction to radiative heat transfer from flames has been presented.
