In this work, applicability of Particle in Cell-Monte Carlo Collisions (PIC-MCC) simulation method for better understanding of the plasma physical mechanisms and real important aspects of a plasma column driven by surface wave plasma discharges that is used in plasma antennas is examined. Via the implementation of geometry and physical parameters of the plasma column to an Object Oriented PIC-M...

the gas-assisted gravity drainage (gagd) process is designed and practiced based on gravitydrainage idea and uses the advantage of density difference between injected co2 and reservoir oil.in this work, one of iran western oilfields was selected as a case study and a sector model wassimulated based on its rock and fluid properties. the pressure of co2 gas injection was close to themmp of the oi...

in the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. the produced liquid flow rate is a function of gas injection rate and injection depth. all the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. also g...

Gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. It occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. Oil phase will form films which are produced under gravity forces (film flow). Many gas injection experiments have been done on laboratory scales with d...

density functional theory calculations were performed to investigate the interactions of nh3 molecules with tio2/mos2 nanocomposites in order to completely exploit the adsorption properties of these nanocomposites. given the need to further comprehend the behavior of the nh3 molecules oriented between the tio2 nanoparticle and mos2 monolayer, we have geometrically optimized the complex systems ...

Cluster galaxies moving through the intracluster medium (ICM) are expected to lose some of their interstellar medium (ISM) through ISM-ICM interactions. We perform high resolution (40 pc) threedimensional hydrodynamical simulations of a galaxy undergoing ram pressure stripping including radiative cooling in order to investigate stripping of a multiphase medium. The clumpy, multiphase ISM is sel...

In this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. CH4, CO2, and H2S, to the various charged particles and syngas in a dielectric barrier discharge (DBD) reactor is studied. An electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. Based on the space...

In this article, a two dimensional pore scale model of polymeric fuel cell, which is promising of a clean and renewable energy production, is presented here. Let reactive gases behave as an ideal gas; inhomogeneous anisotropic structure of the gas diffusion layer, is contemplated as a random generated circular porous media. Lattice Boltzmann method is applied to inquire the fluid flow and mass ...
