Observations of tornadoes in the field and laboratory investigations of tornado-like end-wall vortices have both demonstrated the complexity of this fluid phenomenon. The structure of the core region in particular depends on a number of parameters, one being the swirl ratio (S), i.e the degree of swirl in the background flow (DaviesJones, 1976), another being the degree of roughness of the unde...

The lateral line system of fish consists of superficial neuromasts, and neuromasts embedded in lateral line canals. Lateral line neuromasts allow fish to sense both minute water motions and pressure gradients, thereby enabling them to detect predators and prey or to recognize and discriminate stationary objects while passing them. With the aid of the lateral line, fish can also sense vortices c...

Large eddy simulation of a three-dimensional spatially developing transitional free methane non-premixed flame is performed. The solver of the governing equations is based upon a projection method. The Smagorinsky model is utilized for the turbulent subgrid scale terms. A global reaction mechanism is applied for the simulation of methane/air combustion. Simulation results clearly illustrate the...

High speed electronic devices generate more heat than other devices. This chapter is addressing the portable electronic device air cooling problem. The air cooling limitations is affecting the portable electronic devices. The Multi-Core CPUs will dominate the Mobile handsets Platforms in the coming few years. Advanced control techniques offer solutions for the central processing unit (CPU) dyna...

Centrifugal air classifiers are one of the most used separation devices in particle technology. The study aims to obtain a detailed description bulk material classification mechanism developed centrifugal classifier. classifier design and stable vortex structure formation inter-tube space device described. Velocities within between vortices studied identify regions with inverse flows, which ser...
