Heat transfer enhancement in narrow channels using two and three-dimensional mixing devices.

Author(s) : GARIMELLA S. V., SCHLITZ D. J.

Type of article: Article

Summary

The greatest enhancement in heat transfer relative to the flush heat source was obtained when the roughness elements were used in combination with a single rib on the opposite wall. A peak enhancement of 100% was obtained at a Reynolds number of 11,000, which corresponds to a transitional flow regime. Predictive correlations valid over a range of Prandtl numbers are proposed.
