순수물질의 증발 엔탈피 상관식 개발
Development of a Correlation of the Enthalpy of Vaporization for Pure Substances
증발 엔탈피에 대한 2항 상관식을 제안하였다. 이 상관식을 이용하여 41개 순수물질의 증발 엔탈피 자료를 곡선 접합하였으며 평균 AAD(평균절대편차)가 0.16%이었다. 이는 Xiang(0.30%), Somayajula(0.24%), Guermouche-Vergnaund(0.23%) 등의 기존 상관식보다 우수한 결과이다. 본 연구에서 제안하는 상관식은 데이터가 있는 전 온도 범위에서 쓸 수 있다.
A two-term correlation equation of the enthalpy of vaporization is proposed. The correlation equation is used to fit the enthalpy data for 41 pure substances yielding an average AAD of 0.16%. The result compares with those of conventional equations, such as Xiang(0.30%), Somayajulu(0.24%) and Guermouche-Vergnaund(0.23%). The equation proposed in this work is valid over the entire temperature range where data points exist.
