Abstract

Bu çalışmada, kavite içerisine yerleştirilmiş bir açı verilmiş kare silindirde meydana gelen doğal ve zorlanmış taşınım araştırılmıştır. Çözüm için ticari bir yazılım olan Ansys Fluent program kullanılmıştır. Silindir ilk etapta kavite merkezine yerleştirilmiş, daha sonra ise kavite içerisinde x ekseni boyunca farklı konumlarda bulundurulmuştur. Kavite duvarları yalıtılmış, silindir duvarları ise belli bir sıcaklıkta tutulduğu kabul edilmiştir. Reynolds sayısı 100’den 300’ e, Grashof sayısı ise 103’ den 105’ e kadar değişmektedir. Çalışma akışkanı olarak 0,7 Prandtl sayısında ki özelliklere sahip hava tercih edilmiştir. Nusselt sayısındaki değişim, hız ve sıcaklık izotermlerindeki dağılımlar şekiller ve tablolar vasıtasıyla sunulmuştur

Mixed Convection from Inclined Square Cylinder in a Square Cavity

Year 2022, , 97 - 106, 31.08.2022
https://doi.org/10.46740/alku.1165867

Abstract

In this work, mixed convection from an inclined square cylinder in a cavity is numerically investigated. A commercial CFD solver Ansys Fluent is used to solve the problem. First, the inclined square cylinder is located at the center of the cavity, then the location of the cylinder is changed along the x-axis. The cavity walls are assumed to be adiabatic and the cylinder walls are assumed to be isothermal boundary condition. The Reynolds number, Re varies from 100 to 300 and the Grashof numbers, Gr range from 103 to 105 throughout the work. The working fluid is chosen as air at Prandtl number, Pr = 0.7. The Nusselt number, Nu variations, the distributions of velocity and isotherms are presented in Tables and Figures.
