Bu çalışma, Tauti’nin model kurallarına bağlı kalınarak 1/10 ölçekli modeli yapılan 600 gözlü geleneksel dip trol ağının model deneme sonuçlarını içermektedir. Akıntı tankında, üç farklı çekim hızı (2, 2.5 ve 3 mil/saat) ve üç farklı yüzdürme kuvvetinde (133.4, 96 ve 0 kg) toplam dokuz deneme gerçekleştirilmiştir. Çekim hızına ve yüzdürücü miktarı ile ilişkili olarak ağ geometrisindeki değişiklikler (ağ direnci, dikey ağız açıklığı ve ağız alanı) ölçülmüştür. Çekim hızı artışı ile ağ üzerindeki direncin arttığı, dikey ağız açıklığının azaldığı ve ağ ağız alanında daralma olduğu gözlenmiştir. Çekim hız ile direnç arasında doğru orantılı, dikey ağız açıklığı ile ters orantılı bir ilişki olduğu tespit edilmiştir. Farklı yüzdürücü miktarları ile yapılan testlerde hız ile direnç arasında ilişki R133,4=343.1V1,5, R96=360,2V,.4 ve R0=171,3V1,5 olarak elde edilmiştir. Yüzdürücü miktarındaki artış ağın dikey ağız açıklığını artırmış fakat ağ üzerinde artan bir direnç yaratmıştır. Model ağda elde edilen deneme sonuçlarına göre, gerçek boyuttaki ağ 2-2,5 mil/saat hızda çekilmelidir. Ayrıca, akıntı tankındaki model ağın görüntülerinin incelenmesi sonucunda geleneksel ağın kanat, maça ve model bölümlerinde yapısal iyileştirmelere gereksinim olduğu tespit edilmiştir
