Abstract

Repeated ribs mounted on sidewall in channels are often used to enhance convective heat transfer. In this paper, the heat transfer and fluid flow in a rectangular narrow channel with periodically mounted Longitudinal Vortex Generators (LVGs) on one sidewall was investigated experimentally in the range of Re=3×10³ and Re=2×10⁴. The effect of flow direction on the heat performance was also conducted. It was found that the LVGs are able to greatly improve the comprehensive heat transfer performance. And under three kinds of comparison criterion (Identical Mass Flow-IMF, Identical Pressure Drop-IPD, Identical Pumping Power-IPP), the heat transfer performance of parallel-flow was a little better than that of counter-flow.
