Bu çaly?mada ba?langyçta kapaly kübik hacim olan ön yüzeyinin ortama açylmasyyla kübik bo?luk haline gelen hacimde, arka yüzeyinden ysytma synyr ?artynda do?al ta?ynym laminer durumda deneysel ve teorik olarak incelenmi?tir. Sayysal sonuçlar Fluent 6.3 paket program kullanylarak çözülmü? ve deneysel sonuçlarla kyyaslanmy?tyr. Deneysel çaly?mada do?al ta?ynym ?artlaryny sa?layabilmek için 2x2x1,8 m boyutlarynda ?artlandyrma odasy kullanylmy? deney düzene?inin giri? a?zy bu ?artlandyrma odasyna açylmy?tyr. Çaly?mada akym fonksiyonu, sycaklyk de?i?imi ve hyz vektörleri grafikleri elde edilmi?tir. Ayryca teorik ve deneysel çaly?malar sonucunda Nusselt sayysynyn zamana ba?ly de?i?imi elde edilmi?tir.

In this study, initially off the front surface of a cubic volume of the opening to the environment has become a cubic volume of space in the rear surface heating by natural convection in laminar boundary conditions have been examined in experimental and theoretical case. Numerical results have been solved using Fluent 6.3 program package and were compared with experimental results. Experimental study of natural convection conditions to provide 2x2x1,8 m in size for conditioning room entrance of the experimental setups used in the conditioning room was opened. Study, current function, and the velocity vector graph of temperature changes were obtained. In addition, theoretical and experimental studies of the time-dependent change in the Nusselt number was obtained.
