In this study, Computational Fluid Dynamics (CFD) has been employed to examine the air flow distribution inside Mevlana museum which is one of the important historical places in Turkey. The continuity, momentum and energy equations together with the k-ε turbulence model have been solved using a commercial CFD package. Steady and incompressible flow assumptions have been made to simplify the simulation and reducing the computation time. Sample of the velocity vector plots at different distances from the ground floor of the museum showed circulation zones and vortices at some areas indicating poor air refreshment and possible contaminant emissions. Low velocity areas are also noticeable in some places particularly behind the pillars and any flow obstructs. The dome was found to be a source of enhancing the air flow distribution and flow motion inside the museum. The study concluded that the natural air flow distribution can be improved by different combinations of opening windows and doors based on the wind speed and direction.

Bu çalışmada, Hesaplamalı Sıvı Dinamiği (HSD=CFD), Türkiye’deki önemli tarihi yerlerden birisi olan Mevlana Müzesi’ndeki hava akımı dağılımını araştırmak için kullanılmıştır. Devamlılık, moment ve enerji eşitlikleri ile birlikte k-ε türbülans modeli, ticari CFD paket programı kullanılarak hesaplanmıştır. Durağan ve akışkan akım tahminleri, simülasyonu basitleştirmek ve hesaplama zamanının azaltmak amacıyla yapılmıştır. Müze zemininden farklı mesafelerdeki örnek hız vektör parselleri, sirkülasyon alanları ve bazı girdaplarda zayıf hava tazelenmesini ve muhtemele kirli emisyonlara işaret etmiştir. Özellikle sütün arkaları ve akım engelleyiciler gibi bazı alanlarda düşük hava hız alanları gözlemlenmiştir. Kubbenin müze içerisindeki hava akımını ve hareketini iyileştirici bir kaynak olduğu bulunmuştur. Araştırmada, doğal hava akımının, rüzgar hız ve yönüne bağlı olarak faklı kombinasyonlarda pencere ve kapı açılış kombinasyonları ile iyileştirilebileceği sonucuna varılmıştır.
