대응상태 원리를 응용한 열역학 특성치의 예측 (I) 압축계수
The Prediction of the Thermodynamic Properties by the Use of the Principle of Corresponding States (I) the Compressibility Factors
초록
대응상태 원리를 응용하여 열역학 특성치를 예측할 수 있는 computer program을 개발하였으며 이로부터 methane-ethylene계, carbon dioxide-ethylene계에 대한 2성분계 보정계수를 최적화한 후 이를 사용하여 상기한 2계에 대한 압축계수를 예측한 결과 문헌치로부터 RMS편차가 각각 0.17∼1.23 %, 0.61∼1.24 %의 범위로 나타났다.
A computer program, with which thermodynamic properties can be predited, has been developed employing the principle of corresponding states theory.
Two binary correction parameters are optimized for methane-ethylene and carbon dioxide-ethylene systems. Subsequently the compressibility factors are predicted for the above two systems with RMS deviations of approximately 0.17∼1.23 % and 0.61∼1.24 % range respectively.
