Abstract (2. Language): 
For boundary conditions of constant wall temperature, unsteady natural heat transfer at vertical plate have been investigated as numerically. In this study, laminar boundary layer equations have been solved based on Bousinessq assumption. In the computations, Gr and Re numbers have been taken as variables. By using some programs developed for finite difference and finite element codes for the related equations, the velocity and temperature distributions have been obtained. The obtained numerical results were shown with graphics and tables. Results were compared with similarity and integral methods.

Abstract (Original Language): 
Sabit duvar sıcaklığı sınır şartı altında dikey bir plakada zamana bağlı doğal ısı taşınımı problemi sayısal olarak incelenmiştir. Çalışmada Bousinesq varsayımı ile elde edilen laminer sınır tabaka denklemlerinin çözümü yapılmıştır. Hesaplamalarda Gr ve Re sayısı değişken olarak alınmıştır. Çözülecek denklemlerin sonlu fark ve sonlu eleman karşılıkları yazılarak geliştirilen programlar kullanılarak çözüm düzlemindeki hız, sıcaklık ve basınç dağılımları elde edilmiştir. Elde edilen sayısal sonuçlar grafik ve tablolarla verilmiştir. Benzerlik ve integral çözümleriyle ne denli uyuştuğu karşılaştırmalı olarak verilmiştir.
