Objectives: This study investigates the variation of heat transfer parameters using wavy fin located in the plate heat exchanger. Methods/Statistical Analysis: Velocity and temperature relations, fanning friction factor for iso-temperature and Colburn factor are evaluated for different flow rates of Reynolds Number from 200 to 2000 and its various fin pitches within 9 mm respectively. Similarities were found between this experimental data and semi empirical correlations of Plate Heat Exchanger. Findings: The various parameters are evaluated using this experimental setup and we obtained the optimum j/f for swirl flow regime with Reynolds Number of around 200 to 210. The general correlations for friction factor and Colburn factor were derived by multiple linear regression analysis. Application/Improvements: This studies show the periodic growth of parameters in the wall region of cross section of cross flow heat exchanger. Also we obtained the higher heat transfer co-efficient by using wavy fin with reasonable pressure fall.
