Validation of spectral gas radiation models under oxyfuel conditions

223 Seiten, Dissertation Technische Universität München (2013), Softcover, A5

Zusammenfassung / Abstract

New developed spectral gas radiation models were validated with experimental measurements in a hot gas cell and at a turbulent natural gas flame. The best detailed / simplified model had an accuracy of 2% / 21%. The turbulent flame radiation measurements resulted in negative deviations of the simulations of up to 75% due to the negligence of the turbulence-radiation-interaction. The development of a simple model for the turbulence-radiation-interaction is the most effective way to improve radiative heat transfer predictions in furnaces.
