 In this work, an attempt has made to improve the heat transmit enhancement through winglets in a rectangular canal. The internal surface attachment (wings) has made with the same material of the micro canal. The geometric parameters wing height, wing thickness, and wing patch are considered. For optimizing the geometric parameters L9 orthogonal design of experiments array is used. The 2D analysis of this work is performed in finite volume solver FLUENT. The grid dependent investigation test was conducted to ensure the uncertainty within the demine cells. The output response of the numerical simulation is optimized with sound-to-noise (S/N) ratio. Analysis Of Variance (ANOVA) test was performed to predict the percentage contribution of each factor. Among all the factors, wing thickness contributing more than others. The operational parameter performance of the inlet velocity has been analyzed on the optimized geometry of the micro canal. The results show that the performance of the internal surface attachment improved the heat transfer rate.
