Flow Field Design in Electrochemical Machining of Diffuser

Design of Pneumatic Diffuser System

During non-generation periods, leakage through the wicket gates of a hydroturbine often results in very poor quality water (low or zero dissolved oxygen) in the tailrace of the hydropower facility. Generally, the leakage rate is relatively small, usually about 5-10 cfs per turbine. A bottom-mounted diffuser system was designed based on laboratory-measured and manufacturer-supplied specification...

Numerical Study of Flow Field in New Design Dynamic Cyclone Separators

In this paper the numerical simulation of flow field in the new design dynamic cyclone separator is investigated. The effects of different geometrical parameters such as impeller diameter, number of vanes, length and the location of impeller is investigated. The Reynolds averaged Navier–Stokes equations with Reynolds stress turbulence model (RSM) were solved. The Eulerian-Lagrangian computation...

Mathematical Modelling of Electrochemical Machining Processes

The solution to free boundary problems arising from electrochemical machining processes is considered. A mathematical description of the machining process is presented with particular consideration given to its electrochemical properties and to the appropriateness of its treatment as a potential problem with Dirichlet boundary conditions. A number of different machining configurations are consi...

Laser Drilling Assisted with Jet Electrochemical Machining

Effect of non-uniform Magnetic Field on Non-Newtonian Fluid Separation in a Diffuser

The purpose of the present study is to investigate the boundary layer separation point in a magnetohydrodynamics diffuser. As an innovation, the Re value on the separation point is determined for the non-Newtonian fluid flow under the influence of the non-uniform magnetic field due to an electrical solenoid, in an empirical case. The governing equations include continuity and momentum are solve...
