description | The aim of the research is to investigate heat transfer on concentric tubes on the influence of spiral airflow by using mass transfer analogy. The spiral airflow in the annulus is guided by a spiral fin fitted on the cylinders. In order to investigate the influence of Reynolds numbers and geometry of the concentric tubes, The Reynolds numbers, the ratio of length to the cylinder diameter (Lid), the ratio of outer diameter to inner diameter (D/d) and the ratio of spiral pitch to the cylinder diameter (p/d) were varied. The mass reduction of the specimens due to sublimation were used for calculating the coefficient of mass transfer and the heat transfer coefficient was estimated
from the mass transfer coefficient. The relationship between Nu, Re is Nu = 0.489 Re°-438 (Lid)0.534 (Dm)a.95 0)44.45
Keywords: heat transfer coefficient, cylinder, spiral airflow |
