본 연구의 목적은 물에 대한 판형열교환기의 설계프로그램 개발을 위해 응축열전달계수 및 압력강하에 관한 상관식을 확보하는 것이다. 저온측의 단상유동에 관해서는 Ko의 상관식을 사용하였으며 고온측의응축이 발생하는 이상유동에 대해서는 Annaiev의 상관식과 Lockhart 모델을 적용하여 알고리즘을 제시하였다. 판형열교환기의 운전가능한 범위내에서 상관식의 오차는 상용코드와 비교시 20%이내를 나타냈다.
Abstract
The purpose of this study is to get the formulas of condensation heat transfer coefficient and pressuredrop about the water to develop design program for plate type heat exchangers. The single phase flowof cold side was calculated with the correlation of Ko. Condensation heat transfer coefficient model proposedby Annaiev was used and Lockhart model was used to analyze the pressure drop. The calculation algorithmwas proposed to calculate heat transfer rate and pressure drop simultaneously. The prediction errors remainedwithin 20% compared to the commercial code in the working range of the plate heat exchangers.
