Abstract

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-$\epsilon$ 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.

Özet

Bu çalışmada 8x8 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-$\epsilon$ 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.
