چکیده مقاله:
Equations of State (EOS) are major tools for correlation and prediction of thermodynamic properties of fluids, therefore a large number of publications deal with their development or improvement. In 1899, Dieterici proposed an alternative theoretically based EOS involving an exponential term . There are some advantages in this model, such as a more realistic critical compressibility factor (Z). In this paper, we calculate bulk modulus and study Tait-Marnagan regularity of associating fluids in order to evaluate the performance of equations of state (EOS) based on Dieterici model. The investigated EOSs are Dieterici (D), Dieterici-Carnahan-Starling (DCS) and Dieterici-Guggenheim (DG). Our studies show that the bulk modulus and the regularity are predicted well by EOSs for all substances.
