CFD를 이용한 특수 목적 차량용 Wavy 핀 열교환기 성능에 관한 연구 A Study on the Performance of Wavy Fin Heat Exchangers for the Special Purpose Vehicle using CFD analysis
pp.586-592
The wavy fins have been widely used on the compact heat exchangers in aero system, automotive, air-conditioner and cooler system. The Special Purpose Vehicle has many oil used system and it need cooling system by air in form of fin-flat tube heat exchanger. The objective of this work is to evaluate the performance of wavy fin by Computational Fluid Dynamics(CFD) analysis. 3 modified models were suggested to change protrude direction or to remove blocked surface bot and top of corrugated fin. The base model shows the lowest performance in pressure drop, and modified model 3 shows the highest performance in heat transfer rate. But, modified model 2 has the highest value in the Area goodness factor results, and modified model 3 has the highest value in the Volume goodness factor results.
