Abstract: Numerical simulations and experimental study were carried out to investigate the flow and heat transfer characteristics of air flowing across different types of ovalshaped cylinders, for Reynolds numbers varying from 4000 ...

Abstract: In this paper, the condensation heat transfer characteristics of R134a inside enhanced tubes using two types of surface structures with different materials were investigated, which were then compared with plain tubes under ...

Abstract: To fill the research gaps in the study of flow boiling on composite surfaces, four heat exchange tubes with different structures were investigated: an enhanced tube with herringbone teeth (EHT_HB), a tube with a dimple ...
