Abstract
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

Abstract
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
