Experimental Investigation of Heat Transfer Enhancement in Solid Cylindrical & Cylindrical with Perforated Fins in Staggered & in Inline Arrangements

In this project investigates the heat transfer enhancement in solid cylindrical and cylindrical with perforated fins in inline and staggered arrangement in rectangular channel. The channel had a cross-sectional area of 250- 100 mm2. The experiments covered the following range: Reynolds number 13,500–42,000, the clearance ratio (C/H) 0, 0.33 and 1, the inter-fin spacing ratio (Sy/D) 1.944 and 3.417. Nusselt number and Reynolds number were considered as performance parameters. Correlation equations will be developed for the heat transfer and friction factor. Computational Fluid Dynamics analysis is done by using ANSIS FLUENT 14.5 software. The Numerical and computational analysis shows that the use of the cylindrical perforated pin fins leads to heat transfer enhancement than the solid cylindrical fins. Heat transfer Enhancement varies depending on the clearance ratio and inter-fin spacing ratio. Validation of Numerical and Computational Analysis will be done.
