Abstract

The performance of fin-and-tube heat exchanger is enhanced by modifying fin shape to Wavy fin, fin angle and also material. The conventional resistance on air side is maximum up to 85% of total resistance. This resistance should be minimizing to enhance the heat transfer rate. Wavy fins are particularly attractive for their simplicity of manufacture and potential for enhanced thermal-hydraulic performance. Here performance of wavy-fin and tube heat exchanger is calculated for different temperature and wave angle. CFD analysis is taken for Wavy angle 0°, 10°, 17.44°. Maximum heat flux is 12227 w/m2 for fin angle 17.44° and water inlet temperature 70°C. Heat flux increases with fin angle and also pressure loss increases. Maximum pressure loss is 1.80 Pascal for 17.44° fin angle, water inlet temperature 70°C and air flow velocity 3 m/s.
