強制対流下におかれた底面加熱を受ける傾斜くぼみにおける層流熱伝達

抄録

This study deals numerically with a convective heat transfer in an inclined rectangular cavity with heated from bottom heating surface in a forced laminar Flow. Flow patterns and temperature profiles in the cavity and local and average heat transfer coefficients on the bottom heating surface are presented by Up-Wind difference numerical method for various Reynolds numbers R_eH, Grashoff numbers G_rw and inclination angles θ. It is clarified that the inclination angle has an important role in estimating the Flow pattern and heat transfer in the inclined cavity. It is also understood that the Nusselt number is not increased monotonically with increasing R_eH at G_rw = 2×10³ at low R_eH.
