Flow structure and heat transfer in a channel with multiple longitudinal vortex generators.

Author(s) : TIGGELBECK S., MITRA N., FIEBIG M.

Type of article: Article

Summary

Experimental results of flow structure and heat transfer enhancement by longitudinal vortices in plane channels built by parallel plates in the transition flow regime are presented. The longitudinal vortices are generated by single and double rows of delta half-wing vortex generators punched out of the channel wall. The investigations are performed by a laser light sheet technique for flow vizualization and unsteady liquid-crystal thermography for local heat transfer measurements.
