In this paper the centrifugal pump performances are tested when handling water and viscous oils as Newtonian fluids. Also, this paper shows a numerical simulation of the three-dimensional fluid flow inside a centrifugal pump. For these numerical simulations the SIMPLEC algorithm is used for solving governing equations of incompressible viscous/turbulent flows through the pump. The k-ε turbulenc...

Immiscible displacement of one fluid by another fluid in porous media has important applications in a wide range of different technologies. Most often mentioned is hydrology and and oil recovery. From a theoretical point of view, the displacement process is very complex and hard to describe in detail. Especially, much attention has been paid to the rich variety of displacement structures that i...

In certain geophysical contexts such as lava lakes and mantle convection, a cold, viscous boundary layer forms over a deep pool. The following model problem investigates the buoyant instability of the layer. Beneath a shear-free horizontal boundary, a thin layer (thickness d1) of very viscous fluid overlies a deep layer of less dense, much less viscous fluid; inertia and surface tension are neg...

The vibration of post-buckled fluid-conveying pipe made functionally graded material is analyzed. properties are assumed to be in the thickness direction according power-law distribution. An exact solution obtained for post-buckling deformation with various boundary conditions. linear problem solved around first buckled configuration and natural frequencies three lowest modes obtained. influenc...
