Optimization of Rectangular Winglet on a Channel Flow Using Response Surface Method

Abstract

Enhancement of heat transmission has been a significant study area for a long time. Although
several methods for improving heat transmission have already been developed over the years,
very few studies focus on thermal optimization when vortex generators (VG) are considered.
This study focused on the optimization of a rectangular winglet-type vortex generator in a
channel flow using the response surface methodology. Both experiment and numerical work
are done along with the use of response surface methodology to discover the finest value of
PEC (Performance Evaluation Criteria) of the rectangular winglet on a flat plate in a channel
flow. The range of air velocity and heat power taken is 1 to 6 and 1 to 300 respectively.
Before the optimization, an analysis of variance (ANOVA) is also performed to check the
accuracy of the parameters used. Finally, the optimization is conducted, and the best
performance of PEC that came out is 1.889, which agrees with the outcomes performed
through the experiment.
