Abstract

Desalinasyon işlemi sonucu ortaya çıkan yoğun suyun deniz deşarjı tesisleri yayıcı boruları aracılığıyla alıcı ortamlara kontrollü bir şekilde tahliye edilmeleri için uygun tasarımın yapılması önemlidir. Uygun tasarımın yapılması için yoğun jetlerin alıcı ortamlardaki biçimlerinin ve davranışlarının iyi analiz edilmesi gereklidir. Hesaplamalı Akışkanlar Dinamiği (HAD) modelleri, özellikle son yıllarda yoğun deşarjların modellenmesi ve yoğun jetlerin davranışlarının belirlenmesi için giderek artan bir sıklıkla kullanılmaktadırlar. Bu çalışmada literatürde yoğun deşarjlar üzerine farklı HAD yazılımları ve türbülans modelleri kullanılarak yapılmış çalışmalar sistematik olarak incelenmiştir. Çalışmanın ana amacı, farklı deşarj koşulları altında değişen parametrelerin yoğun jetlerin geometrik karakteristikleri ve karışma ve seyrelme süreçleri üzerindeki etkilerinin incelenmesidir. Ek olarak farklı HAD yazılımları ve türbülans modellerinin performanslarının karşılaştırılması ve değerlendirilmesi de hedeflenmiştir. Sonuçlar değişen deşarj parametrelerinin jetlerin biçimleri ve davranışlarını önemli ölçüde etkilediğini göstermektedir. Farklı deşarj ve alıcı ortam koşulları altında farklı modellerin değişken performanslar göstermektedir. En uygun performansı veren modelin kullanımının optimum tasarımı yapabilmek adına önemli olduğu görülmektedir.

A Review of Computational Fluid Dynamics (CFD) Modeling Studies On Dense Discharges

Abstract

Appropriate design of marine outfalls is of utmost importance for the safe disposal of brine, which is the byproduct of the desalination process. A thorough analysis of brine jet behavior and mixing and dilution in ambient environments is required for the optimum design. For these analyses, Computational Fluid Dynamics (CFD) models have been increasingly used in recent years. In this paper, studies carried out on dense discharges using different CFD software and turbulence models are systematically reviewed. It was aimed to investigate the effects of differing discharge parameters on brine jet behavior and dilution and to evaluate and compare the performances of different CFD software and turbulence models. Results revealed that differing discharge parameters affect brine jet behavior and dilution significantly; different models performed differently under altering discharge and ambient water conditions, and the use of the most suitable model for optimum discharge is important.
