Experimental Study and Three-Dimensional Numerical Flow Simulation in a Centrifugal Pump when Handling Viscous Fluids

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...

Self-organization and symmetry-breaking in two-dimensional plasma turbulence

The spontaneous self-organization of two-dimensional magnetized plasma is investigated within the framework of magnetohydrodynamics with a particular emphasis on the symmetry-breaking induced by the shape of the confining boundaries. This symmetry-breaking is quantified by the angular momentum, which is shown to be generated rapidly and spontaneously from initial conditions free from angular mo...

Self-organization phenomena and decaying self-similar state in two-dimensional incompressible viscous fluids.

The final self-similar state of decaying two-dimensional (2D) turbulence in 2D incompressible viscous flow is analytically and numerically investigated for the case with periodic boundaries. It is proved by theoretical analysis and simulations that the sinh-Poisson state comega=-sinh (betapsi) is not realized in the dynamical system of interest. It is shown by an eigenfunction spectrum analysis...

Response to ‘ ‘ Comment on ‘ Sonoluminescence light emission ’ ’ ’ † Phys . Fluids 12 , 472 „ 1999 ... ‡

In their Comment, Hammer and Frommhold check the validity of the results in the original publication by comparing the approximate calculations found therein to their ab initio, quantum mechanical formalism. Overall, both computational methods yield similar results, which validates the assumptions about the principal physical processes involved in SBSL light emission ~electron–ion and electron–n...
