Abstract
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 cooling by natural convection laminar boundary conditions have been examined in experimental and theoretical case. Numeric results using Fluent 6.3 package dissolved and experimental results are compared with. Experimental study of natural convection conditions to provide 2x2x1,8 m size used in the conditioning chamber experimenty of the entrance of this mechanism has been opened to the conditioning room. Study, current function, and the velocity vector graph of temperature changes were obtained. Also as a result of theoretical and experimental study of the Nusselt number time dependent difference was found.
Abstract
Bu çaly?mada ba?langyçta kapaly kübik hacim olan ön yüzeyinin ortama açylmasyyla kübik bo?luk haline gelen hacimde, arka yüzeyinden so?utma synyr ?artynda, laminer durumda do?al ta?ynym 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 2x2x1,8m 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 bulunmu?tur.
