低レイノルズ数形κ-εモデルによる吹出しのあるチャネル乱流の数値計算

抄録

A numerical calculation is performed on the turbulent channel flows with uniform injection using five different low-Reynolds-number κ-εmodels. Published experimental data on the mean velocity profiles, the Reynolds shear stress, and the friction velocity are used to assess the performance of the model calculations. Applicabilities of these models to turbulent channel flows with injection are investigated. Fof flow with injection, the κ-εmodel proposed by Launder and Sharma gives good agreement with the experimental data. Also, the effects of the inlet velocity and the channel width on those flows are examined using the model which provides most accurate prediction.
