Numerical Analysis for Heat Transfer Augmentation in a Circular Tube Heat Exchanger Using a Triangular Perforated Y-Shaped Insert

The present investigation constitutes CFD analysis of the heat transmission phenomenon in a tube exchanger with Y-shaped insert triangular perforation. is accomplished by considering air as working fluid Reynolds number ranging from 3000 to 21,000. segment considered for consists circular 68 mm diameter and 1.5 m length. geometrical parameter perforation index (0%, 10%, 20%, 30%). constant flux provided at wall pressure-based solver used solution. studies are performed analyzing effects inserts on transfer friction factor which results augmented higher (PI) lower factor. show that highest 5.84 times over simple plain maximum thermal performance (TPF) 3.25 PI = 30%, Re 3000.
