Overview of convection and radiation in high temperature gas flows

A literature overview is presented of radiative and convective heat transfe r in high temperature gas flows. The primary thrust is on fundamentals, but current technological applications of the complex phenomena involving, not only spectrally selective radiative transfer in common gases, but also tur bulent chemically reacting flows, are discussed. The infrared radiation gas property models and methods for solving the radiative transfer equation ar e highlighted first. Then, convective and radiative heat transfer in channe ls and chemically reacting high temperature hows are reviewed. The nonlinea r effects of turbulent fluctuations in radiative transfer, and the influenc e of radiation on thermal turbulence spectra are also considered. Critical issues which need to be addressed for a more complete understanding of the processes are raised, and topics requiring research attention are identifie d. (C) 1998 Elsevier Science Ltd.
