The development of particle-enriched regions (bed-load) at the base of particle-laden gravity currents has been widely observed, yet the controls and relative partitioning of material into the bed-load is poorly understood. We examine particle-laden gravity currents whose initial mixture (particle and fluid) density is greater than the ambient fluid, but whose interstitial fluid density is less...

Almost all computational fluid dynamics (CFD) simulations of flow around marine propellers use turbulence models that are only well suited for fully turbulent flows, which in some cases may lead to accuracy degradation in the prediction of propeller performance characteristics. The discrepancy between computed thrust and torque and corresponding experimental data increases with increasing prope...

In this era of globalization, technology is developing rapidly, which means that it will also have an impact on the increasing use electrical energy. Electrical energy consumption not only limited to household consumers, but a small and large industrial scale. We recognize need for load flow study in planning good power system determine best operating system. The method used solving Newton-Raph...
