(2011-03-15)Cooling of electronic components is one of the most important issues concerned in the electronic industry for design of equipment. Maintaining the temperature of an electronic device within its safe operating temperature ... -
Role Of Solid Phase Movement And Remelting On Macrosegregation And Microstructure Formation In Solidificaiton Processing
(2010-08-25)Melt convection and solid phase movement play an important role in solidification processes, which significantly influence the formation of grain structures and solute segregations. In general, the melt convection and grain ... -
Sedimentation Of Heavy Particles In Turbulence
(2010-08-06)Behavior of particles in buoyancy driven turbulent flow at Ra ≈ 10º is investigated experimentally. The volume fraction of the particles is low enough for the inter particle influence to be neglected, the mass loading ... -
Semisolid Die Casting of Wrought A6061 Aluminium Alloy
(2018-04-02)The mechanical properties achieved with high performance wrought aluminium alloys are superior to cast aluminum alloys. To obtain an intricate shaped component, wrought alloys are commonly subjected to forging followed by ... -
A shape optimization approach for simulating contact of elastic membranes with rigid obstacles
The obstacle problem consists in computing equilibrium shapes of elastic membranes in contact with rigid obstacles. In addition to the displacement u of the membrane, the interface on the membrane demarcating the ... -
Shock Dynamics due to Downstream Pressure Perturbations: Idealization of Transonic Unstarted Cascade Flutter
Shock wave unsteadiness is an important phenomenon in high-speed aerodynamics. This phenomenon is observed in many locations of high-speed vehicles, such as supersonic inlets, ramjet engines, transonic airfoils, high-speed ... -
Shock Wave-boundary Layer Interaction in Supersonic Flow over Compression Ramp and Forward-Facing Step
(2018-01-12)Shock wave-boundary layer interactions (SWBLIs) have been studied ex-tensively due to their practical importance in the design of high speed ve-hicles. These interactions, especially the ones leading to shock induced ... -
Simple Models For The Mean And Transient Intertropical Convergence Zone And Its Northward Migration
(2011-11-16)Satellite data have shown that east-west oriented cloud bands, known as Intertropical convergence zone (ITCZ), propagate eastwards along the equator throughout the year and northwards during boreal summer on intraseasonal ... -
