Özet:

 Free surface flow around bridge piers is one of the most important problems of open channel hydraulics. The structural design of the bridge should be done correctly along with the hydraulic design by simulating the water surface around the bridge piers together with the scour that will occur around the bridge piers. If the hydraulic design of the bridge piers is not good enough, it can cause very serious damages in situations such as floods and overflows. The aim of this paper is to analyze the effect of bridge piers on the water surface experimentally and numerically. For the numerical analysis, FLOW-3D, a computational fluid dynamics package program that performs 3-dimensional solution, and HEC-RAS package program are used and the results are compared. In the study, flows with the same velocity for different number of bridge openings were studied and compared with the experimental results. In addition, the FLOW 3D package program, which performs solutions with the finite volume method, was compared with the experimental results by performing solutions with different mesh sizes. As a result, it was observed that the solutions performed with the FLOW-3D package program showed very close results with the experimental data.

 Köprü ayakları etrafındaki serbest yüzeyli akım, açık kanal hidroliğinin en önemli problemlerinden biridir. Köprünün yapısal tasarımı, köprü ayakları etrafında oluşacak oyulma ve köprü ayakları etrafındaki su hareketini simüle eden hidrolik tasarım ile birlikte doğru bir şekilde yapılmalıdır. Köprü ayaklarının hidrolik tasarımı yeterince iyi değilse, sel ve taşkın gibi durumlarda çok ciddi hasarlara neden olabilir. Bu çalışmanın amacı köprü ayaklarının su yüzeyine etkisini deneysel ve sayısal olarak analiz etmektir. Sayısal analiz için hesaplamalı akışkanlar dinamiği ile 3 boyutlu çözüm yapan FLOW-3D paket programı ile HEC-RAS paket programı kullanılmış ve sonuçlar karşılaştırılmıştır. Çalışmada farklı köprü açıklık sayıları için aynı hızda akışlar incelenmiş ve deneysel sonuçlarla karşılaştırılmıştır. Ayrıca sonlu hacimler yöntemi ile çözüm yapan FLOW 3D paket programında farklı mesh boyutları ile çözüm yapılarak deneysel sonuçlar ile karşılaştırılmıştır. Sonuç olarak FLOW-3D paket programı ile gerçekleştirilen çözümlerin deneysel veriler ile oldukça yakın sonuçlar gösterdiği gözlemlenmiştir.
