Özet:

 Timing is vital for oil spill response operations. However, deployment of the traditional response equipment, unfortunately, takes much more time. Therefore, innovative solutions are needed to minimize time losses. One of these innovative solutions is the air bubble barrier. Air bubble barrier creates a barrier to anything floating in the water, especially keeping the floating oil and petroleum in the area where it is spilled. Computational Fluid Dynamics simulation has grown in importance as a resource for air bubble barrier studies in recent years. Despite the extraordinary success of Reynolds Averaged Navier-Stoke applications on air bubble barriers, just a few studies concentrate on mesh sensitivity, one of the most fundamental issues with CFD methods. The main purpose of this study is to perform a mesh convergence study by simulating an air bubble barrier in the Simcenter STAR CCM software. In this context, in this simulation, a 2D numerical model is considered. The mesh convergence study has been performed by calculating the aperture inlet mean static pressure and the mean horizontal surface velocity. As a result, it is evident that the mesh base size and number of elements in mesh in case 10 can be employed to maintain the solution time-optimal state in the upcoming numerical simulations on the 2D and 3D air bubble barrier. Case 10 represents the mesh base size of 0.015 and the number of elements in mesh of 99042. Findings from this parametric study will be incorporated as mesh control rules into the subsequent 2D and 3D simulations of the air bubble barrier.

 Petrol sızıntısı müdahale operasyonları için zamanlama çok önemlidir. Ancak, geleneksel müdahale ekipmanının konuşlandırılması maalesef çok daha fazla zaman almaktadır. Bu nedenle, zaman kayıplarını en aza indirgemek için yenilikçi çözümlere ihtiyaç vardır. Bu yenilikçi çözümlerden biri de hava kabarcığı bariyeridir. Hava kabarcığı bariyeri, suda yüzen her şeye karşı bir bariyer oluşturur, özellikle yüzen petrolü ve petrolü döküldüğü alanda tutar. Hesaplamalı Akışkanlar Dinamiği simülasyonu, son yıllarda hava kabarcığı bariyeri çalışmaları için bir kaynak olarak önem kazanmıştır. Hava kabarcığı bariyerlerinde Reynolds Ortalamalı Navier-Stokes uygulamalarının olağanüstü başarısına rağmen, HAD yöntemlerinin en temel sorunlarından biri olan ağ hassasiyetine odaklanan çok az çalışma vardır. Bu çalışmanın temel amacı, Simcenter STAR CCM yazılımında bir hava kabarcığı bariyerini simüle ederek bir ağ yakınsama çalışması yapmaktır. Bu kapsamda bu simülasyonda 2D sayısal model ele alınmıştır. Ağ yakınsama çalışması, nozul girişi ortalama statik basıncı ve ortalama yatay yüzey hızı hesaplanarak gerçekleştirilmiştir. Sonuç olarak, 2D ve 3D hava kabarcığı bariyeri üzerinde gelecek sayısal simülasyonlarda çözüm süresi-en uygun durumunu korumak için durum 10daki ağ taban boyutunun ve ağ elemanı sayısının kullanılabileceği açıktır. Durum 10, 0.015lik ağ taban boyutunu ve 99042lik ağdaki eleman sayısını temsil eder. Bu parametrik çalışmadan elde edilen bulgular, ağ kontrol kuralları olarak hava kabarcığı bariyerinin sonraki 2B ve 3B simülasyonlarına dahil edilecektir.
