This work focuses on SGS modeling in the energy equation. High correlation is found between the SGS heat flux q(sub j)(sup L) of modified Leonard term form and the exact SGS heat flux, but not between the SGS heat flux of Salvetti's model and the exact SGS heat flux. Therefore, an improvement is required for the calculation of the model coefficient. In the filtered energy equation, the numerical evaluation results show that the SGS turbulence diffusion term and the SGS heat flux term are dominant during the transition process, the SGS turbulence diffusion term is the most dominant first and the SGS heat flux term in the turbulent stage of the jet. The calculated correlation coefficient suggests that the pressure dilatation term correlate well with the SGS heat flux., 資料番号: AA0047776007, レポート番号: JAXA-SP-04-002}, pages = {21--24}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {圧縮性乱流DNSデータベースを用いたSGSモデルの評価}, volume = {JAXA-SP-04-002}, year = {2005} }
