Numerical Analysis of the Effect of Serrated Fin to the Heat Transfer in the Condenser

Abstract

Heat transfer efficiency improvements have been conducted in various methods. Increasing surface area by installing serrated fin will increase exchanger efficiency. This research uses the numerical method of CFD 2D to compare tube heat transfer without and with a serrated fin on 7 m/s and 9 m/s Velocity. A serrated fin with an outer diameter of 0,03175 m has 0° and 30 segments per period. Give inlet parameter 350.15 °K, resulting in outlet serrated fin tube temperature lower than the annular tube (without serrated fin). Simulation Serrated fin tube an inlet velocity of 7 m/s resulting outlet temperature of 343.2 °K, lower than tube simulation which produces outlet temperature of 344.53 °K.
