Abstract

Flow characteristics around side by side square prisms with control rods are numerically investigated atdifferent gap ratios (g*) changing between 0.5 and 6 for Re = 73. Four different flow patterns, whichare single street mode, irregular street mode, regular street mode and two street mode, are identifiedbased on the gap ratio. Maximum drag reduction (%52) is obtained at g* = 6. The mean lift coefficienthas a symmetric variation between these gap ratios for the upper and lower square prisms. It can beconcluded that the control rod is an effective flow control method in terms of drag reduction.

Özet

Kontrol çubuklu yan yana kare prizmalar etrafındaki akış karakteristikleri, Re= 73 için g* = 0.5 - 6 aralığında değişen boşluk oranlarında nümerik olarak incelenmiştir. Tekli, ikili, düzensiz ve düzenli girdap caddesi olmak üzere dört farklı akış modeli boşluk oranlarına bağlı olarak tanımlanmıştır. Maksimum sürükleme azalması (%52) g* = 6’da elde edilmiştir. Ortalama kaldırma katsayısı, alt ve üst kare silindir için boşluk oranları arasında simetrik değişim göstermiştir. Kontrol çubuğunun sürükleme kuvvetini azaltması açısından etkili bir akış kontrol yöntemi olduğu sonucu çıkarılabilir.
