Abstract

Two-phase flow in pipes is often encountered in engineering applications. Liquid and gas flowing in a pipe of different cross-sectional area is a simple' example of two-phase gas-liquid flow. In this study, gas-liquid flows in horizontal concentric and eccentric pipes have been examined to fill up the deficiency in the literature. In the first step, the observed flow patterns have been compared with the flow pattern maps ofWeisman and Baker. Especially slug flows have been examined in a detailed manner using both empirical calculation methods and experimental results. Differences of flow patterns between concentric, eccentric and circular pipe flow parameters have been examined. Particularly, variations of flow regimes with respect to gas and liquid flow rates and eccentricity of two pipes have been determined.

Özet

Mühendislik uygulamalarında sıkça meydana gelen iki fazlı akışa en basit örnek, bir boru içerisinde gaz ve sıvının beraberce almasıdır. Bu çalışmada, yatay konsantrik ve eksantrik borular içindeki iki fazlı gaz-sıvı akışları incelenmiş ve literatürdeki bir eksikliğin giderilmesine çalışılmıştır. İlk olarak, gözlemlenen akış rejimleri Baker ve Weisman'nın akış diyagramlarına göre değerlendirilmiştir. Bu çalışmada özellikle heyelanlı akış tipi incelenmiştir. Konsantrik veya eksantrik yatay bir boru içindeki çift fazlı gaz-sıvı akışı ile dairesel yatay bir boru içindeki gaz-sıvı akışı arasındaki farklar araştırılmıştır. Gaz ve sıvı debileri, iç içe iki boru arasındaki eksantrisite değiştirilerek, akış rejimlerinde meydana gelen değişmeler araştırılmıştır.
