Advantage of SWET Technique on Joining Inconel 792 Material
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 12 Issue: 6
Inconels 792 are nickel-base superalloy material that has high strength and creep resistance at temperature near their melting point. This material is commonly used in aircraft gas turbine (jet) engines, where parts or components are subjected to high temperature and high stress. Not-withstanding the high-temperature capabilities of the alloys, during service the parts are often damaged ...

Numerical Modeling of Surface Roughness in Grinding under Minimum Quantity Lubricants (MQL) using Response Surface Method (RSM)
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 12 Issue: 5
Grinding is primarily a finishing operation where high temperature at the wheel-work interface adversely affects the physical properties of the ground surface in terms of induced surface and sub surface residual stress, surface roughness, micro cracks and dimensional deviation. Conventional application of cutting fluid often cannot control the high temperature generated especially during...

CFD Analysis of Intake Valve for Port Petrol Injection SI Engine
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 12 Issue: 5
The air standard efficiency for SI engine is approximately 60% under full load condition but the actual brake thermal efficiency under full load condition is approximately 32.6% which is due to the various losses that occur. One of the primary lose is burning time loss which is approximately 4% and occur due to finite time combustion of the charge. This lose can be reduced to some extend...

A Computational Approach on the Position of Load Centre of a Slipper Bearing
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 12 Issue: 5
The slipper bearing is an integrated part of an axial piston pump. Proper lubrication is important for successful operation of the slipper bearing. This type of bearing is a type of hydrostatic thrust bearing. Many works have been done in the recent past on this type of bearing. This current work is based on the theoretical investigation of the locus of the load centre of this type of be...
