Geçiş kanallarında entropi üretiminin deneysel olarak incelenmesi

Bu çalışmada, hava akışının dikdörtgen kesitli bir kanalda kare kesitli bir kanala geçişi sırasında, türbülanslı akış şartlarında entropi üretimi deneysel olarak incelenmiştir. Deneylerde Reynolds sayısı $2.10^5 leq Re leq 6.10^5$ aralığında değiştirilmiştir. En büyük sürtünme katsayısı en kısa geçiş borusunda, elde edilmiştir. Entropi üretiminin geçiş kanalının eşdeğer koniklik açısının büyümesiyle ile artığı belirlenmiştir.

Experimental investigation of entropy generation in transition channels

In this study, entropy generation was investigated experimentally while air flow passing from rectangular channel to square in turbulent flow conditions. Reynolds number was varied between $2.10^5 leq Re leq 6.10^5$. In experiments the biggest friction factor was obtained the smallest transition duct. Entropy generation was increased according to transition duct equivalent conical angle.
