ShareEffect of surface roughness of micro-scale hatched tubes on the absorption performance.
Author(s) : CHO H. C., KANG Y. T., KIM C. D., et al.
Summary
This work was aimed at investigating the effect of surface roughness of micro-hatched tubes on the absorption performance and to develop an experimental correlation of the Nusselt number as a function of the roughness. Three different micro-scale hatched tubes and a bare tube were tested to quantify the effect of the surface roughness on the absorption performance. It was found that the absorption performance of micro-hatched tubes was improved up to twofold compared with the bare tube. An experimental correlation of Nusselt number was developed as a function of the Reynolds number of the film and the roughness, with an error band of approximately 25%.
