“…The As-values are closely related to the viscosity of the system in vapour-phase, [9] which is greater in DMA-rich region than that of MOE and can assume that the DMA molecules bounding are more correlated and ordered in vapour state. Furthermore, the correlation curve of these two properties show linear behaviour for some other previously studied binary mixtures such as water with isobutyric acid (IBA), [10,11] 1,4-dioxane [9] and N,Ndimethylacetamide with 2-ethoxyethanol (EOE), [1] water, [12] formamide (FA), [13] N, N-dimethylformamide (DMF) [14] and methanol (Met), [15] and DMF with (Met). [16] The pre-exponential entropic factor (As) equivalent to the viscosity at infinite temperature (As = η ∞ ) is very closely related to the viscosity of the same system in vapour-phase at the normal boiling temperature and at the same pressure.…”

Calculation of excess properties in N,N-dimethylacetamide + 2-methoxyethanol binary mixtures at (298.15, 308.15 and 318.15) K from experimental density, viscosity and sound velocity values were presented in previous work. Applications of these experimental values to test different correlation equations as well as their corresponding relative functions were also reported. Considering the quasi-equality between the Arrhenius activation energy Ea and the enthalpy of activation of viscous flow ΔH*, here we can define partial molar activation energy Ea 1 and Ea 2 for N,N-dimethylacetamide and 2-methoxyethanol, respectively, along with their individual contribution separately. Correlation between Arrhenius parameters reveals interesting Arrhenius temperature with a comparison to the vaporisation temperature in the liquid vapour equilibrium, and the limiting corresponding partial molar properties that can permit us to estimate the boiling points of the pure components.

“…The imbibition result from Figure 4 will give further explanation. Also, according to Haj-Kacem et al [33], can be closely related to the viscosity of the pure system in vapor state at the same studied pressure [34][35][36][37]. From the results of experiment, 1 and 2 can be derived, so 1 and 2 are approximately the viscosity of L1 and L2 systems at vapor state under the working pressure, if any some molecules pass in vapor state and mix with the gas fluid.…”

The fracturing fluid-gas spontaneous displacement during the fracturing process is important to investigate the shale gas production and formation damage. Temperature and slippage are the major mechanisms underlying fluid transport in the micro-/nanomatrix in shale, as reported in the previous studies. We built a fracturing fluid-gas spontaneous displacement model for the porous media with micro-/nanopores, considering two major mechanisms. Then, our spontaneous displacement model was verified by the experimental result of the typical shale samples and fracturing fluids. Finally, the influences of temperature, slip length, and pore size distribution on the spontaneous imbibition process were discussed. Slippage and temperature significantly influenced the imbibition process. Lower viscosity, higher temperature, and longer slip length increased the imbibition speed. Ignoring the temperature change and slippage will lead to significant underestimation of the imbibition process.

“…Case of pure components: For phenomenological discussion of the causal correlation, we have proposed an extra endogenous variable such as the viscosity Arrhenius temperature (T A ) where the reciprocal value is determined by the intercept to abscissa axis (1/T A ) or using the following equation: Table-2 summarizes the viscosity Arrhenius parameters of some solvents studied in previous works [21][22][23][24][25][26]35,39,41,[44][45][46][47][48][49][50] and Fig. 3 indicates mutual correlation between the parameters (Ea, ln As and TA) of Arrhenius.…”

“…In addition, we can consider roughly the linear behaviour which is also noticed for some other studied binary liquid mixtures like water with 1,4-dioxane or isobutyric acid or DMA, etc. [2,6,[20][21][22]25,[44][45][46][47][48][49][50].…”

“…Furthermore, the close dependence on composition, between the molar enthalpy of viscous flow (∆H*) and the viscosity activation energy (Ea) guided to considering that (Ea) is approximately a thermodynamic state function for which partial quantities have been determined to arise individual interaction's contributions of each pure solvent within the fluid mixture for each mole composition and the new given parameter nominated as the current Arrhenius temperature (TAi) related to each pure solvent (i) can provide in a reliable estimation of the boiling point value of the two pure solvents constituting the studied binary fluid mixture [20,21,[44][45][46][47][48][49][50].…”

The experimental values of absolute viscosity in N,N-dimethylformamide + ethanol binary fluid mixtures (from 303.15 to 323.15 K) can induce us to investigate different correlation expressions as well as their derivative quantities. Investigation of the molar enthalpy of viscous flow (∆H*) and the viscosity activation energy (Ea) reveals close values and similar variation against composition, here we can justify the notion of partial activation energies Ea1 and Ea2 for pure components along with their separately individual contributions. Correlation between the two Arrhenius parameters in the whole range of compositions shows the existence of different interaction behaviours, delimited by peculiar compositions. It is also noticed that the ratio between the two parameters leads to the Arrhenius temperature which is in causal correlation with the temperature of vapourization in the liquid-vapour isobaric diagram and the limiting partial properties can permit us to predict values of the boiling temperatures of the pure fluid components.
