Summary

A study was done on how heat transfer can be promoted by machining slots on the disk-type heat transfer surface and dividing it into lots of sector-shaped sections, through theoretical analysis and numerical simulation. Numerical simulation, which includes only the effect of heat conduction in the liquid layer, shows a good agreement with experiments reported in other literature. Also, it turned out that the prediction equation yielded by theoretical analysis gives not only the qualitative explanation of the increase of heat flux, but also the quantitative prediction on the heat flux with an adequate accuracy. Summarizing those results, the enhancement of heat transfer can be apparently achieved according to the number of splits.
