本文以非結構性網格探討空氣在梯形區域內部之自然對流情況，以流場及溫度分佈瞭解局部熱傳情形，矩形及梯形區域與數值標準解比較相當接近，當萊利數達10^6時，與Kuyper和Hoogendoorn之數值結果不同。 This work studies for natural convection of air in differentially heated, trapezoidal enclosures based on unstructured grids. Numerical predictions are presented for flow patterns and isotherms to further understand the local heat transfer. Numerical results are correlated well with benchmark solutions in a rectangular domain and a trapezoidal domain. When the Rayleigh number is 10^6, a different observation is obtained than that of Kuyper and Hoozendoorn.
