アスペクト比変化が水平対流の時空間的伝熱特性に及ぼす影響の評価

抄録

In natural convection heat transfer, the flow is driven by density differences caused by temperature differences. In horizontal convection, different temperature fields are set on the horizontal plane, and the buoyancy is generated along the horizontal direction. In this study, the dependence of convection formation on the aspect ratio of the box is evaluated by numerical analysis and experiments. The analysis confirmed that horizontal convection is formed by the inflow of cooled fluid to the heated surface. Furthermore, when the aspect ratio was changed, the transition of the heat transfer coefficient was consistent and the value itself was almost the same. Visualization of horizontal convection through experiments also suggested the validity of the numerical analysis.
