Heat transfer analysis in fin and tube exchanger using CFD

Abstract The designs of fine tubes and thermal exchangers rely on the fabrication of copper and aluminum fin and tube heat exchangers. The heat was regulated through copper tubes and pipes by flowing water. The major objective of this work will be to enhance the rate of heat transmission by altering the existing tube and finish. The copper U-tube was replaced with the spline fin in the heat exchanger in this project. Pressure drop, speed, and heat transfer properties of the heat exchanger were evaluated using solid works and the study was conducted using computer fluid dynamics (CFD). From the results, it has been determined that the improvement of thermal transfer rate and efficiency in spline fin is up to 5 percent higher than the flat fin and also increases pressure and the higher pumping power in a heat exchanger by placing fluid within the fin through cross-flow.
