The emphasis of this study is to make clear the effect of the brick surfaces and arrangement on the total performance of the heat storage tank. A plain surface brick with two types different positions i.e. incline and parallel with the stream flow were studied. The brick was heated by hot air 50℃ and velocity 0.1m/s from initial condition 20℃. Laminar, transient and two-dimensional governing equations are solved by using SIMPLE algorithm. The calculation results show that the presence of the dimples on brick surfaces did not enhance the heat transfer rate from the air into the brick. The incline position of the brick tow and upstream enhances the heat transfer rate significantly. Based on these results a full scale heat storage systems consist of a sets of plain bricks were also studied. As expected, the heat storage tank with inclined positions of bricks reveal the better performance of storing heat from the hot air compared to the parallel position.}, pages = {537--542}, title = {蓄熱槽中の蓄熱要因レンガの表面形状と配列に対する熱伝達および流れ特性の研究}, volume = {21}, year = {2005}, yomi = {スズキ, ジュン and キシナミ, コウキ and ダイマルヤ, マサシ and マツサカ, サトル} }
