The experiments have also shown that there is some difference between the drag forces corresponding to longitudinal-grove roughness elements and uniform sand roughness elements for the same height.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:In this study, the effects of the longitudinal-groove roughness elements (placed on the outer surface of the pipe) on the drag force acting on the pipe were experimentally investigated and compared with uniform sand roughness.
📊
Key Findings & Data:The experimental results have indicated that the drag force exerted by the flow on a pipe increases as the distance between the canal bottom and the pipe and the height of roughness elements increases and it decreases as the distance between two successive longitudinal-groove roughness elements decreases.

Abstract

In this study, the effects of the longitudinal-groove roughness elements (placed on the outer surface of the pipe) on the drag force acting on the pipe were experimentally investigated and compared with uniform sand roughness. The experimental results have indicated that the drag force exerted by the flow on a pipe increases as the distance between the canal bottom and the pipe and the height of roughness elements increases and it decreases as the distance between two successive longitudinal-groove roughness elements decreases. The experiments have also shown that there is some difference between the drag forces corresponding to longitudinal-grove roughness elements and uniform sand roughness elements for the same height.

Özet

Bu çalışmada, boru dış yüzeyine yerleştirilen boyuna yivli pürüzlülüğün, boruya etkiyen sürükleme (direnç) kuvveti üzerindeki etkisi deneysel olarak incelenmiş ve üniform kum pürüzlülük ile karşılaştırılmıştır. Deney neticeleri göstermiştir ki, boruya etkiyen sürükleme kuvveti borunun tabanla olan mesafesi ve pürüzlülük elemanlarının yüksekliği arttıkça artarken, yiv genişliği azaldıkça azalmaktadır. Ayrıca aynı yükseklikteki boyuna yivli pürüzlülük ve üniform kum pürüzlülük elemanlarına sahip boruya etkiyen sürükleme kuvvetleri arasında bir miktar fark olduğu görülmüştür.
