Farklı hücum açılarında akış ayırıcı plakalı bir kare prizmaya etki eden kaldırma ve sürükleme kuvvetleri yük hücresiyle ölçülerek deneysel olarak incelenmiştir. Sonuçlar, kaldırma ve sürükleme katsayılarının Re = 9700 – 36500 aralığında 0°, 45°, 90°, 135° ve 180° hücum açıları için Reynolds sayısından bağımsız olduğunu göstermiştir. Sürükleme katsayısı 0° hücum açısında tek kare prizma için 2.02 ve ayırıcı plakalı kare durumunda ise 1.04 olarak elde edilmiştir. Plakalı kare için maksimum sürükleme katsayısındaki azalma 50% olarak 0° ve 15°’de elde edilmiştir.  α <30° ve α >114° aralıkları için, plakalı karenin sürükleme katsayısı sade karenin sürükleme katsayısından küçüktür. Re = 20000’de, kaldırma ve sürükleme katsayılarının önemli derecede hücum açısına bağlı olarak değiştiği görülmüştür. 

Lift and drag forces on a square prism with a (splitter) plate are experimentally investigated by force measurements with a load cell. Results showed that drag and lift coefficients are independent of Reynolds number for Re = 9700 – 36500 at 0°, 45°, 90°, 135° and 180°. Drag coefficient at 0° is obtained as 2.02 for the square prism alone, and 1.04 for the square cylinder with splitter plate. Maximum drag reduction for the square cylinder with the plate is 50% as compared to the square cylinder at 0° and 15°. For α < 30° and α > 114°, drag coefficient of a square prism with splitter plate is smaller than that of the square prism alone. At Re = 20000, lift and drag coefficients significantly change with increasing attack angle.
