摘要
The interaction between turbulence in a minimal supersonic channel and radiative heat transfer is studied using largeeddy simulation. The working fluid is pure water vapour with temperature-dependent specific heats and molecular transport coefficients. Its line spectra properties are represented with a Statistical Narrow Band correlated-k (SNB-cK) model. Computations with a fictitious gray gas resulting in a higher optical thickness are also performed. Results for the mean flow variables, Reynolds stresses and certain terms of their transport equations indicate that thermal radiation effects counteract compressibility effects.
