EFFECT OF PURE WATER AND PURE ALCOHOL ON FILMWISE AND DROPWISE CONDENSATION

Condensation is a process which we come across with in many fields. In this study, the condensation experiments for pure water and pure alcohol as distinct from the studies in the literature were carried out. In the condensation test, the change of surface heat transfer coefficient, heat flux and heat transfer rate have been experimentally investigated with respect to the difference between the saturation temperature and the surface temperature for a known test device. The experiments have been conducted separately for a film and drops of condensation flow. According to the results obtained from the experiments, experimentally and theoretically calculated surface heat transfer coefficients have been presented in a tabulated form. In addition, the surface heat transfer coefficient, the heat flux and the heat transfer rate changes by the difference between saturation and surface temperatures have been presented in diagrams.

Yoğuşma, birçok ısıtma ve soğutma prosesinde karşımıza çıkan bir prosestir. Bu çalışmada, saf su ve literatürde yer alan çalışmalardan farklı olarak saf alkol için yoğuşma deneyleri yapılmıştır. Yoğuşma deneyinde, bilinen bir deney cihazı üzerinde yüzey ısı transfer katsayısının, ısı akışının ve ısı transfer hızının, doyma sıcaklığı ve yüzey sıcaklığı arasındaki farka göre değişimleri deneysel olarak incelenmiştir. Deneyler film ve damla akışlı yoğuşma için ayrı ayrı yapılmıştır. Deneylerden elde edilen sonuçlara göre deneysel ve teorik olarak hesaplanan yüzey ısı transfer katsayıları tablolar halinde sunulmuştur. Bunun yanında, yüzey ısı transfer katsayısı, ısı akısı ile ısı transfer hızlarının doyma ve yüzey sıcaklıkları arasındaki farka göre değişimleri diyagramlar halinde gösterilmiştir.
