W artykule przedstawiono wyniki badań doświadczalnych procesu wrzenia węglowodorów wyższych podczas ich spływu cienkim filmem po powierzchni walca poziomego. Badania przeprowadzone zostały dla trzech czynników: n-pentanu (R601) i n-heksanu (R602) i heptanu (R603) w szerokim zakresie gęstości strumienia ciepła. Powierzchnie robocza stanowił mosiężny walec o średnicy zewnętrzne) 18 mm. Na podstawie...
The effect of eddy diffusivity upon the turbulent film condensation of saturated vapour flowing downward onto a horizontal isothermal circular tube is performed theoretically by employing the Hilpert semi-empirical model. The interfacial shear of the vapour from laminar flow to turbulent flow is evaluated with help of potential flow theory. The transition region or the separation point of condensate...
The results of investigations in flow patterns of two-phase liquid-liquid flows in horizontal pipes with diameters of 12, 16 and 22 mm have been presented in the paper. Water and two types of oil, i.e., machine oil, lighter than water, and tar oil, heavier than water, were investigated. As a result of conducted studies, the observed flow patterns were described, defined and named, moreover they were...
