The minimum miscibility pressure (MMP) is one of the crucial and substantial parameters in the gas injection projects for enhanced oil recovery (EOR). This parameter indicates the minimum pressure at constant temperature and composition conditions for reaching 100 percent of the oil production recovery which leads to a huge economic income. Therefore, an inaccurate prediction of the MMP may lea...

We calculate the maximum mass of the class of compact stars described by VaidyaTikekar [24] model. The model permits a simple method of systematically fixing bounds on the maximum possible mass of cold compact stars with a given value of radius or central density or surface density. The relevant equations of state are also determined. Although simple, the model is capable of describing the gene...

Hydrogen (H2) is a clean fuel and key enabler of energy transition into green renewable sources method achieving net-zero emissions by 2050. Underground H2 storage (UHS) prominent offering permanent solution for low-carbon economy to meet the global demand. However, UHS complex procedure where containment security, pore-scale scattering, large-scale capacity can be influenced contamination due ...

A correlation based on the general form of cubic equations of state has been derived. This equation provides a convenient mathematical form of the Joule-Thomson coefficient in terms of the state variable V and T. The Joule-Thomson coefficient calculated by this correlation has been compared with experimental data. It has been shown that the Redilich-Kwang equation of state is a suitable equ...

In this paper, we find all the solutions of the Diophantine equation x + 2 513 = y in nonnegative integers x, y, α, β, γ, n ≥ 3 with x and y coprime. In fact, for n = 3, 4, 6, 8, 12, we transform the above equation into several elliptic equations written in cubic or quartic models for which we determine all their {2, 5, 13}-integer points. For n ≥ 5, we apply a method that uses primitive diviso...

a viscosity model, based on eyring’s absolute rate theory combined with a cubic pr equation of state and wong-sandler mixing rule, has been proposed in order to correlate viscosities of aqueous solutions of alkanolamine mixtures at atmospheric pressure and different temperatures. in the proposed method, the energy and size parameters in studied equation of state (eos) have been obtained using t...
