垂直な加熱平板列まわりに生じる自然対流の流動と伝熱 : 平板枚数の影響(熱工学,内燃機関,動力など)

Natural convective flows of water induced around a horizontal row of vertical heated plates were investigated both analytically and experimentally. In order to analyze the whole flow and temperature fields around the row, full elliptic equations were solved in a large computational domain that encloses the row. Heat transfer and flow visualization experiments were also carried out to ascertain the present analysis. The results showed that the present analysis well predicts the actual flow field and heat transfer from the plates. It was also found that the velocity profiles and flow rates within vertical slots bounded by the plates vary not only with the location of slots in the row but also with the total number of plates. These variations also result in a marked difference in the local and overall heat transfer coefficients of the plates.
