For example, Carbon dioxide (CO2 ) may be injected into an oil reservoir in orderto improve the oil recovery rates, which is called enhanced oil recovery (EOR).<\/p><p>An upscaling methodology for modeling multiscale features of the flow and the porous medium has been studied, where the overall pressure drag and skin friction exerted on the porous medium has been modelled by combining the Darcy\u2019s law with a statistical mechanical theory of viscosity.<\/p><p>A numerical methodology for capturing the multi-physics and multiscale nature of the governing motion has been studied. The temporal discretization employs the second order Crank-Nicolson scheme for viscous and diffusive phenomena, and an explicit method for all other terms. The nonlinear advection terms in the momentum equation has been treated with an Euler explicit flux form central finite difference method; however, the advection of the CO 2 mass flux has been treated with a streamline based Lagrangian method. In order to implement the Marker-and-Cell (MAC) scheme for resolving the incompressibility, a staggered arrangement of the velocity and pressure has been presented on a collocated grid. This approach enhances the implementation of a multigrid solver, and is a novel computational model for simulating miscible displacement processes. The performance of the Lagrangian method has been assessed with respect to an equivalent flux form upwind method.<\/p><p>The results indicate that the viscous forces play a significant role compared to the effect of permeability on miscible displacement of CO 2 and oil, where the injected CO2 displaces the residual oil without being distorted, thereby enhancing the recovery of hydrocarbon. Although the present results with an idealized model lacks from verifications with field measurements, findings of this thesis provide useful feedback to further investigations on CO 2 based EOR techniques.<\/p><p>The modeling of simultaneous flow behavior through a reservoir and wellbore is important and an integrated model is needed which accounts for the transient multiphase flow in the wellbore and its surrounding region. In addition, reservoir and wellbore interface modeling and cost-effective Computational Fluid Dynamics (CFD) methodology are required to simulate the flow behavior in that region.<\/p><p>The study outlines the development of an experimental prototype to study multiphase flow in the near wellbore region. To the best of my knowledge, this facility has the capability to accommodate a larger length scale compared to similar facilities available in the research organizations. This experimental setup can be used for investigating with a wide variety of multiphase flow problems which have been considered in the present research.<\/p><p>A CFD methodology has been developed using the 3D Navier-Stokes equations to simulate an integrated wellbore-reservoir flow. The CFD methodology has been verified for the fluid flow mechanism at near wellbore. The simulations results have been compared to the analytical solutions. Then, this model is extended to establish a coupled wellbore-reservoir framework which is based on 3D Navier-Stokes equations. The simulations have been performed to validate the newly developed CFD algorithm and various scenarios of a reservoir have been taken into consideration. The same process has been applied to investigate flow through a perforated tunnel and a new method of perforation has been discussed.<\/p><p>The study indicates standard CFD techniques use a \u201cnumerical approach\u201d such as the volume of fluid accounts for capillary pressure and surface tension force for the flow through porous media. Allen-Chan phase-field method has been combined with the Navier-Stokes equations to simulate multiphase flow in porous media. The simulations performed with the phase-field method have been verified with the experimental data. The experimental and CFD approach of this thesis make a unique contribution in the field of the petroleum industry and multiphase flow in porous media.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>\u00a0 KEYNOTE SPEAKER 1 PROFESSOR DR USMANOV PAZLITDIN NURITDINOVICH\u00a0Head of Physics Department, Namangan Institute of Engineering and Technology Presentation : The properties of even\u2013even deformed nuclei Abstract Insufficient knowledge of the properties of strong interactions and the absence of rigorous methods for calculating systems consisting of tens and hundreds of strongly interacting particles forced theorists [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"_links":{"self":[{"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/pages\/70"}],"collection":[{"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/comments?post=70"}],"version-history":[{"count":171,"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/pages\/70\/revisions"}],"predecessor-version":[{"id":1647,"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/pages\/70\/revisions\/1647"}],"wp:attachment":[{"href":"https:\/\/conference.iium.edu.my\/icmae\/2024\/index.php\/wp-json\/wp\/v2\/media?parent=70"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
