Shape optimization of rib-roughened surface to enhance turbulent heat transfer.

Author(s) : KIM K. Y., KIM S. S.

Type of article: Article

Summary

This work presents an investigation on numerical optimization technique coupled with Reynolds-averaged Navier-Stokes analysis of flow and heat transfer for design of rib-roughened surface in case of single surface roughened in two-dimensional channel. Standard kappa-epsilon model is used as a turbulence closure. The objective function is defined as a function of heat transfer coefficient and friction drag coefficient with weighting factor. The ratio of width-to-height of the rib and the ratio of pitch-to-height are selected as design variables.
