Abstract (2. Language): 
In this study natural convection in a cavity with a block mounted on a vertical wall was investigated numerically. The effects of the placement and, the dimensions of block on natural convection were studied. The block mounted vertical wall was warmer than the outer vertical wall and block itself was insulated perfectly. A SIMPLEM algorithm was used based on finite control volume approach for calculations. Calculations were performed in the range of 103 <Ra<105 . It was found that the block mounted on the wall have significant effect on natural convection heat transfer and flow field.

Abstract (Original Language): 
Düşey duvarına blok monte edilmiş oyuk içerisinde, bloğun yeri ve boyutunun doğal taşınım üzerindeki etkisi sayısal olarak incelenmiştir. Bloklar tamamen yalıtımlı ve blok yerleştirilmiş düşey duvarın diğer duvara göre daha sıcak olduğu kabul edilmiştir. Problem için zamana bağlı olmayan çözümler elde edilmiştir. Hesaplamalar Rayleigh sayısının 104 <Ra<106 değerleri için yapılmıştır. Düşey duvara yerleştirilen bloğun doğal taşınım akış hareketi ve ısı transferini büyük ölçüde etkilediği tespit edilmiştir.
