Effect of Non-uniform Heating on Forced Convective Flow Through Asymmetric Wavy Channel

We explore the heat transfer characteristics for forced convective flow of a Newtonian fluid through the wavy channel under the effect of non-uniform heat flux. The findings are presented for different values of Reynolds number (Re) and dimensionless wavelength of the non-uniform heating \((\gamma)\) in the range of 100 \(\le\) Re \(\le\) 500 and 0.25 \(\le\gamma\le\) 4, respectively. The non-uniform heating decreases the hot spot intensity in the circulatory flow zone and moreover it induces additional maxima of Nusselt number as compared to the constant heating case. The average Nusselt number for sinusoidal heating case is much more than the constant heating case for the smaller undulation of the non-uniform heating.
