Abstract (2. Language): 
In this study, the pressure drop of helical square duct which has 8x8 mm dimension, a pitch of b =12 mm was investigated both experimentally and numerically with the similar experimental boundary conditions. SIMPLE algorithm, PRESTO pressure-velocity interpolation option, RNG k-e turbulent model and Gauss Siedel iteration method were used in numerical computations which were done by FLUENT® programme. As a result it was understood that the maximum difference between numerical and experimental data is about 5 %. The experimental and numerical results were compared and validated with the results in the literature.

Abstract (Original Language): 
Bu çalışmada 8 x 8 mm kare kesitli, 12 mm hatveli helisel kanalda basınç düşüşü deneysel olarak tespit edilerek benzer sınır şartlarında bilgisayarda nümerik çözüm yapılmıştır. Nümerik çözüm FLUENT® programı ile SIMPLE çözüm algoritması, PRESTO basınç-hız enterpolasyon yöntemi, RNG k-e türbülans modeli ve Gauss Siedel iterasyon metodu kullanılarak yapılmıştır. Nümerik ve deneysel veriler arasında en fazla % 5 gibi bir fark vardır. Deneysel ve nümerik sonuçlar literatürde yayınlanmış çözümler ile karşılaştırılarak valide edilmiştir.
