Aspen Plus能不能计算流股的熵？ aspen plus 中的熵是用来估算gibbs函数的。这个就是熵估算的目的。至于基准可以自己调整，但是如果调整后，就必须给出相应的参数。详细的情况看下面的说明： adjusting reference states for tabular data and polynomials aspen plus can adjust the reference state of the enthalpy, entropy, and gibbs free energy data that you entered. to specify this: on the tabpoly specifications sheet, deselect the do not adjust reference state check box for your tabular data or your polynomial data. specify the basis (mole or mass) for your reference value and for the data, in the basis list box. on the reference points sheet, select the component for which you want to adjust the reference state, in the component list box. in the reference points boxes enter a reference temperature and a reference value for enthalpy, entropy, or gibbs free energy. if you want to enter reference values and have aspen plus generate entropy and gibbs free energy data from the enthalpy or heat capacity data that you enter, you must enter reference values for two of the three properties. the reference values are at the same temperature. to use the aspen plus default reference state, do not enter any data on the reference points sheet. however, you must supply these parameter values for (or they must be available in the databanks): dhform, dgform, plxant dhvlwt (or dhvldp) the aspen plus thermodynamic reference state is the component's constituent elements in an ideal gas state at 25°c and 1 atm.查看更多
