Investigation of Two-phase Flow Behavior to Determine Fracture Relative Permeability in the Models of Fractured Porous Media: Experimental and Simulation Study
, M.Sc. Thesis Sharif University of Technology ; Ghazanfari, Mohammad Hossein (Supervisor)
Abstract
The behavior of two-phase flow in porous media is influenced by the flow functions. Especially in fractured porous media where the relative permeabilities of the phases in the fracture and matrix are different, the flow behavior is significantly affected by these functions. On the other hand, the properties of the fluid and the fracture, such as length, orientation, and roughness of the fracture, also play an important role in determining the values of relative permeabilities and, consequently, the behavior of two-phase flow. However, the influence of fracture geometric properties on the relative permeability curves in fractured porous media is not well understood. In this study, firstly, a...

Abstract
Feed-in tariff (FiT) is one of the most efficient ways that many governments throughout the world use to stimulate investment in renewable energies (REs) technology. For governments, financial management of the policy could be challenging as it needs a considerable amount of budget to support RE producers during the long remuneration period. In this paper, it has been illuminated that the early growth of REs capacity could be a temporary boost. And the socio-economic structure of the system will backlash the policy if some social mechanisms are not considered. Social tolerance for paying REs tax and potential investors’ trust emanated from budget-related mechanisms -which have rarely been...
