A numerical investigation has been performed to study the effect of eccentricity on unsteady state, laminar aiding mixed convection in a horizontal concentric and eccentric cylindrical annulus. The outer cylinder was kept at constant temperaturewhile inner heated with heat flux. involved solution transient momentum (Navier-Stokes) energy equation using finite difference method (FDM), where body...

Bimetal pipes are highly stressed composite components that must resist corrosion in a chemically aggressive environment. They made by welding resistive material to commonly available carbon steel pipes. The production of pipe bends with supercritical bend 0.7D, which part serpentine systems, is very complex and technologically demanding because often undesired cracks occur. To increase the ser...

Internal convective cooling is a method by which components, such as gas turbine blades, are protected from damage caused by elevated temperatures. Heat pipes are structures that transport and dissipate large quantities of pressurized thermal energy. The thermal energy is transported from a heat source to a thermal sink via evaporative cooling. A radially rotating high temperature heat pipe . e...

The Next Linear Collider (NLC) uses a damping ring for the electron beam, a pre-damping ring and a main damping ring for the positron beam to reduce the beam emittances. The requirements of the main damping ring kickers are to bend a 2 GeV beam by an angle of 2 mrad over a length of 1.2 m. This results in a required field of 139 G. The magnet aperture is 30×30 mm. The predamping ring kicker req...
