초록

알루미늄 플레이트-핀 열교환기는 석유 및 가스 처리공정에서 널리 사용되고 있다. 알루미늄 플레이트-핀 열교환기의 성능은 각 유체의 헤더 및 분배기에서의 분배 성능에 의하여 크게 영향을 받는다. 본 연구에서는 CFD(Computational fluid dynamics)를 이용하여 알루미늄 플레이트-핀 열교환기의 측면 입구 형태의 분배기를 모델링하고, 입구 조건과 형상비의 변화에 따른 상대 및 절대 불균등 분배도를 고찰하여 최적 분배기 형상비를 제시하였다.

Aluminum plate-fin heat exchangers (ALPHEs) are widely used in petroleum and gas-treated processes. The performance of the ALPHE is strongly dependent on the distribution characteristics of the header and the distributors of each fluid. In this paper, we define the aspect ratio in the side-entry type distributor and analyze the distribution characteristics using CFD-based numerical methods. The phenomena of velocity deviation and distribution with the aspect ratio and the inlet Reynolds number were analyzed by applying relative and absolute maldistribution parameters, and an optimum aspect ratio with the inlet Reynolds number was presented.
