Abstract

Kavite akışı içerisinde dönen adyabatik bir silindir varlığının akış yapısı ve ısı transfer üzerindeki etkisinin incelendiği sayısal bir çalışma gerçekleştirilmiştir. Çalışmada uzunluk ve derinlik oranı (D/L) 2 olan açık bir kavite içerisine 0.025m çapa sahip adyabatik bir silindir yerleştirilmiştir. Silindir kavite içerisinde 11 farklı konuma yerleştirilmiş ve bu konumlarda 6 farklı dönme hızı tanımlanmıştır. Silindir çapı ile tanımlanan Reynolds sayısı 10000 olarak belirlenmiştir. Isı transfer analizi için kavite duvarlarına 10000 W/m^2 değerinde sabit ısı akısı uygulanmış, sonlu hacimler yöntemi kullanılarak çözümlemeler yapılmıştır. Çalışmanın sonuçları kavite içerisinde silindirin kullanılmadığı boş kavite akışı olarak ifade edilmiş olan durum dikkate alınarak incelenmiştir. Boş kavite akışına nispeten silindire farklı konumlarda tanımlanan dönme hızları akış yapısını ve ısı transferini iyileştirici yönde etki sağladığı gözlemlenmiştir.

ACTIVE FLOW CONTROL INSIDE AN OPEN CAVITY WITH ROTATING CYLINDER: NUMERICAL INVESTIGATION OF HEAT TRANSFER AND FLOW CHARACTERISTICS

Abstract

A numerical study is carried out to examine the effect of the presence of an adiabatic cylinder rotating in the cavity flow on the flow structure and heat transfer. In the study, an adiabatic cylinder with a diameter of 0.025 m is placed in an open cavity with a length to depth ratio (D/L) of 2. The cylinder is placed in 11 different positions in the cavity and 6 different rotational speeds are defined in these positions. The Reynolds number defined by the cylinder diameter is determined as 10000. For heat transfer analysis, a constant heat flux of 10000 W/m2 is applied to the cavity walls and analyzes are made using the finite volume method. The results of the study are examined by considering the situation expressed as empty cavity flow where the cylinder is not used in the cavity. It has been observed that the rotational speeds defined in different positions to the cylinder relative to the empty cavity flow provide an improvement in the flow structure and heat transfer.
