Nonlinear Effect in-flow in Porous Duct
(2013-05-13)In general, it is assumed in some non viscous flows that the flow velocity is constant at a cross-section. In this thesis, If we impose more realistic boundary conditions by, for example, introducing viscosity,and suction ...

Numerical Modeling of Wellbore Instability (TENSILE Failure) Using Fracture Mechanics Approach
(2013-05-12)When a well is drilled, the equilibrium in-situ stress is changed. In order to support the stress relief induced by the drilling and to prevent hydrocarbon influx into the cavity, the borehole is filled with a fluid. These ...
