Modelling and Simulation of Low-Head Hydro Turbine for Small Signal Stability Analysis in Power System

The hydro turbine dynamics have a considerable influence on the dynamic stability of power system. In the study of dynamic stability, the system is modeled by the linear differential equations (small  signal analysis). Small signal stability of power systems is needed in all conditions and only is dependent on the conditions of power system performance before commotion occurrence. This paper pr...

Multiphase flow and tromp curve simulation of dense medium cyclones using Computational Fluid Dynamics

Dense Medium Cyclone is a high capacity device that is widely used in coal preparation. It is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in DMCs complex. In this article the flow pattern simulation of DMC is performed with computational fluid dynamics and Fluent...

2D Simulation of High-Efficiency Cross-Field RF Power Sources

In a cross field device[1] such as magnetron or cross field amplifier electrons move in crossed magnetic and electric fields. Due to synchronism between electron drift velocity and phase velocity of RF wave, the wave bunches the beam, electron spokes are formed and the bunched electrons are decelerated by the RF field. Such devices have high efficiency (up to 90%), high output power and relativ...
