Studies On Transport Phenomena During Solidification In Presence Of Electromagnetic Stirring
(2010-07-20)In several applications of casting, dendritic microstructure is not desirable as it results in poor mechanical properties. Enhancing the fluid flow in the mushy zone by stirring is one of the means to suppress this dendritic ... -
Studies on Two-Stage Air-Cooled Silica gel + Water Adsorption Cooling System
Adsorption cooling systems are evolving as promising complements to conventional vapor compression refrigeration (VCR) systems because of their ability to utilize low-grade heat sources such as industrial waste heat, solar, ... -
Studies on Vortex Breakdown in a Closed Cylinder with a Rotating Endwall
(2018-01-09)Swirling flows abound in nature and numerous engineering applications. Under conditions which are not completely understood, the swirling cores could undergo a sudden enlargement of their vortex core, leading to a ’vortex ... -
Study And Design Of Two-Thirds Power Weir
(Indian Institute of Science, 2006-07-17)This thesis is devoted to the study and designs of two important proportional weirs having the discharge-head characteristics of Q α H 2/3 In the first design a geometrically simple weir in the form of a rectangular weir ... -
A Study Of A Vortex Particle Method For Vortex Breakdown Phenomena
(2010-07-06)Vortex breakdown is an important phenomenon observed in swirling flows involving the development of a stagnation point on the axis of the vortex followed by a region of recirculation when the swirl increases beyond a ... -
A Study Of Crystallographic Texture, Residual Stresses And Mechanical Property Anisotropy In Aluminium Alloys For Space Applications
(2013-05-21)Aluminium alloys, which are the most widely used materials in the aircraft and aerospace industries, find their applications due to high strength–to-density ratio, resistance to catastrophic fracture, high degree of ... -
