Effect of design factors on the performance of heat exchanger with a slit fin

슬릿휜형 열교환기의 성능에 대한 설계인자의 영향

This study is to systematically analyze the effect of various kinds of design parameters on heat transfer and pressure drop characteristics of heat exchanger with a slit fin. TAGUCHI method, known to us as a very reasonable tool in the parametric study, is employed in the present work. Experimental factors have been limited to seven cases, considering the production of sample and the cost. The 18 kinds of large scale models are made by compounding level on each factor and the heat transfer and flow characteristics on each model has been analyzed. The present results allow us to be able to quantitatively estimate the various parameters affecting the heat exchanger performance, and main factors for an optimum design of a heat exchanger have been selected. The optimum design value on each parameter was presented and the reproducibility on the results was guaranteed.
