A theory of wave propagation in fractured porous media is presented based on the double-porosity concept. The macroscopic constitutive relations and mass and momentum balance equations are obtained by volume averaging the microscale balance and constitutive equations and assuming small deformations. In microscale, the grains are assumed to be linearly elastic and the fluids are Newtonian. Momentum transfer terms are expressed in terms of intrinsic and relative permeabilities assuming the validity of Darcy's law in fractured porous media. The macroscopic constitutive relations of elastic porous media saturated by one or two fluids and saturated fractured porous media can be obtained from the constitutive relations developed in the paper. In the simplest case, the final set of governing equations reduce to Blot's equations containing the same parameters as of Blot and Willis.

Body waves in fractured porous media saturated by two immiscible Newtonian fluids
Tuncay, Kağan (Springer Science and Business Media LLC, 1996-06-01)
A study of body waves in fractured porous media saturated by two fluids is presented. We show the existence of four compressional and one rotational waves. The first and third compressional waves are analogous to the fast and slow compressional waves in Riot's theory. The second compressional wave arises because of fractures, whereas the fourth compressional wave is associated with the pressure difference between the fluid phases in the porous blocks. The effects of fractures on the phase velocity and atten...
Wave propagation in fractured porous media saturated by two immiscible fluids
Corapcioglu, MY; Tuncay, Kağan (1998-01-01)
A study of wave propagation in fractured porous media saturated by two immiscible fluids is presented, based on the double-porosity concept. The macroscopic constitutive relations and mass and momentum balance equations are obtained by volume averaging the microscale balance and constitutive equations, and assuming small deformations. Momentum transfer terms are expressed in terms of intrinsic and relative permeabilities assuming the validity of Darcy's law in fractured porous media. In the simplest case, t...
Comparison of Fenitrothion and Trifluralin Adsorption on Organo-Zeolites and Activated Carbon. Part II: Thermodynamic Parameters and the Suitability of the Kinetic Models of Pesticide Adsorption
LÜLE ŞENÖZ, Güzide Meltem; Atalay, Mustafa Ümit (Informa UK Limited, 2014-07-04)
The suitability of two kinetic models and the thermodynamic parameters of pesticide adsorption were investigated based on obtained data of previous studies. Kinetic evaluation indicated that the pesticides adsorption on adsorbents followed the pseudo-second-order model. Gibbs free energy (Delta G degrees), enthalpy (Delta H degrees), and entropy (Delta S degrees) were calculated for thermodynamic parameters by using linearized Arrhenius equation. The results indicated that the sorption process of fenitrothi...
CO2 injection into saline carbonate aquifer formations I: laboratory investigation
Izgec, Omer; Demiral, Birol; Bertin, Henri; Akın, Serhat (Springer Science and Business Media LLC, 2008-03-01)
Although there are a number of mathematical modeling studies for carbon dioxide (CO2) injection into aquifer formations, experimental studies are limited and most studies focus on injection into sandstone reservoirs as opposed to carbonate ones. This study presents the results of computerized tomography (CT) monitored laboratory experiments to analyze permeability and porosity changes as well as to characterize relevant chemical reactions associated with injection and storage of CO2 in carbonate formations....
Photocatalytic and photoelectrochemical water splitting over ordered titania nanotube arrays
Karslıoğlu, Osman; Üner, Deniz; Department of Chemical Engineering (2009)
The objective of this study was to investigate photocatalytic water splitting over ordered TiO2 nanotube arrays. Synthesis of ordered nanotube arrays of titania, as a micron thick film on a titanium foil was accomplished by electrochemical anodization methods defined in the literature. Effect of two types of electrolyte (aqueous and organic) on the micro-morphology was observed by scanning electron microscopy. Optimum anodization times for the TiO2 nanotube electrodes, synthesized in ethylene glycol electro...
