By introducing the mixing rule, only molecular weight and acentric factor and critic parameters of each components are required as input. 该模型通过引入混合规则,仅需输入混合工质各组分的分子量、偏心因子和临界参数即可预测混合工质的粘度和导热系数。
Wiener Number was found to be a good measure of acentric degree of molecular structure. A proportional relationship between Pit-zer acentric factor and Wiener Number for paraffins was established. The relationship can be used to predict Pitzer acentric factor of isomeric alkanes. 发现Wiener数是一个能够很好地衡量分子结构偏心程度的拓扑指数,在Pitzer偏心因子与Wiener数之间存在着很好的比例关系,据此能够预测异构烷的偏心因子。
