Fluid flow in microtubes with axial conduction including rarefaction and viscous dissipation
Cetin, Barbaros; Güvenç Yazıcıoğlu, Almıla; KAKAÇ, SADIK (Elsevier BV, 2008-05-01)
Graetz problem inside the microtube is revisited considering rarefaction effect, viscous dissipation term and axial conduction in the fluid for uniform wall temperature boundary condition in the slip flow regime. The flow is assumed to be hydrodynamically fully developed, thermally developing, and the velocity profile is solved analytically. The temperature field is determined by the numerical solution of the energy equation. The rarefaction effect is imposed to the problem via velocity-slip and temperature...
Fluid-CO2 injection impact in a geothermal reservoir: Evaluation with 3-D reactive transport modeling
AKIN, TAYLAN; Baser, Ali; Saracoglu, Onder; Akın, Serhat (2022-01-01)
Geothermal energy is commonly recognized as an environmentally friendly source of energy. However, geothermal fluids have unusually high CO2 content, particularly, in carbonated geothermal reservoirs. An efficient method to mitigate the CO2 emissions of geothermal power plants is to re-inject the captured CO2 with the effluent fluid to mineralize mainly into calcite under reservoir conditions (e.g., reservoir temperatures ranging from 200 to 220 degrees C). One of the major concerns about the re-injection o...
Fluid flux throughout matrix-fracture interface: Discretizing hydraulic fractures for coupling matrix Darcy flow and fractures non-Darcy flow
Al-Rbeawi, Salam; Owayed, Jalal F. (Elsevier BV, 2020-01-01)
The objective of this paper is focusing deep insights on reservoir fluid flux from a structurally complicated matrix to non-uniformly propagated hydraulic fractures. A hypothetical unconventional reservoir is considered with stimulated and un-stimulated reservoir volume. A Semi-analytical multilinear flow regimes model is developed for pressure distribution by coupling matrix Darcy flow model and hydraulic fracture non-Darcy flow model. Hydraulic fractures are discretized to several segments with a specific...
Flow visualization and determination of temperature distribution in inclined channels
Sağlamcı, Abdülaziz Mehmet; Bayer, Özgür; Department of Mechanical Engineering (2018)
Subway transportation systems play an important role in human life in this century. Millions of people make use of subway transportation every day in metropolises. In subways, there is a very crucial situation "case of fire and smoke generation" that must be prevented. In subway areas, it is known that stairs are used to connect the ground with the subway area, metro stations in other words. Stairs have an angle with the ground horizontal called as tilt angle. The most important case of smoke movement in ca...
