Almost all of the structural failures occur due to cracks propagation. Holes, cavities, inclusion are perfect site for crack nucleation and growth ultimately leading to fracture. However, holes are sometimes inevitable in structures to provide some functionality. In the present study an investigation has been made to ascertain the parameter that would play a role i...

In the present work, Computational Fluid Dynamics (CFD) analysis of solar air heater having artificial wavy roughness has been performed. Ansys FLUENT software is used as a simulation tool for CFD analysis. Twelve different configurations of the wavy surface having rib height (e) 0.7 mm, 1 mm and 1.4 mm and pitch (p) of 10, 15, 20 and 25 mm have been considered as ...

Gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) processes are an efficient economical means of welding of ferrous and non-ferrous materials. GMAW and GTAW processes have a great potential for application in precision welding of aluminium alloy 3003-H2. The published literature reveals that no systematic effort has been made to study the GMAW and GT...
