タイトル(掲載誌)航空宇宙技術研究所特別資料 = Special Publication of National Aerospace Laboratory SP-15
一般注記Numerical simulation of thermal convection in a horizontal rectangular duct flow heated from its bottom and side walls is conducted using a method based on the Fourier spectral method. As a result, it is seen that the convective secondary flow is induced not only by the Rayleigh-Benard convection but by the natural convection near the side walls. When Reynolds numbers are rather larger values, 500 and 220, we have almost stationary longitudinal convective rolls in the flow. On the other hand, when the Reynolds numbers are smaller values, 90 and 50, the rolls fluctuate chaotically in space and time; then the time-averaged secondary flow is almost vanishing and the fluid temperature widely constant in the central part of the flow.
