Authors: bhise Nishita , Ramachandran M. 
Published: May 2020

Abstract
The crankshaft is an engine component that converts the linear (reciprocating) motion of the piston into rotary motion. Features of a crankshaft include the crankpin journal, throw, bearing journals, counterweights, crank gear, and a power take-off (PTO). Crankshafts are machined through a sequence of automated operations that remove material using lathes and milling machines. Other off-the line processes include inspection, test and repair. High-count cylinder engines involve higher inertias, overlapping combustion events and torsional vibrations of the flexible crankshaft which strongly complicate the diagnostics. The equivalent inertias and stiffness’s of the system were calculated from drawings, modelling of the crankshaft with a CAD (computer-aided design) software and finite element method. Crankshaft is Internal cylinder pressure (or torque) estimation is an important engine parameter with significant implications for diagnostic and control applications in internal combustion (IC) engines. Many speed-based diagnostics methods employ models of the engine dynamics. In a dynamic model of a small four-cylinder diesel engine with the assumption of a rigid crankshaft is employed to estimate individual cylinder power production.

Authors: Verma Rajesh , Gupta Krishna Kumar 
Published: May 2020

Abstract
Nanofluids are emerging as more suitable heat transfer fluid compare to conventionally used fluids for transferring heat in various engineering applications. Nanofluid is a fusion of very small quantity of nanoparticles and host fluid with considerable stability. The presence of nanoparticles in host fluid significantly enhance its thermal conductivity, which leads to the improvement in thermal performance. Introduction of submicron particles influence the viscus behaviour of the host fluid. In general viscosity enhancement is not desirable as it imposes a penalty in terms of increased pumping power in many engineering applications. Presence of more than one type of nanoparticles in host fluids provide opportunities to enhance thermal conductivity with control over other properties of resultant nanofluid. The nanofluid having more than one type of nanoparticles termed as hybrid nanofluid are in focus of researchers for investigation. A large variety of hybrid nanofluids are prepared and their properties investigated by various researchers. This review paper is an attempt to compile the research work related to preparation techniques, stability analysis and thermophysical properties of hybrid nanofluids. The potential applications of hybrid nanofluids and challenges associated with it are also discussed.

Published: May 2020

Abstract
Laser hardening is one of the reasonable procedures utilized to improve surface mechanical and wear resistance of target materials. This process is easy to use for improving surface properties of complex shape components with minimum time requirement. The beauty of this process is that it is possible to improve only selective surface properties without altering the remaining surface properties of bulk material. Ck45 steel has various important properties like hardness, superior wear resistance and frictional performance etc. These properties are useful in various industrial applications. The existing study is an attempt to analyse results on surface properties with the aid of process parameters of a laser hardening process on hardness depth and microstructure of laser hardened Ck45 steel the use of a design of experimental approach. From this analysis, it can be summarized that the depth of the surface layer hardness is maximized by controlling the laser beam power, laser scan speed and standoff distance, which improves the service life of Ck45 steel components hardened by laser. Comparing the experimental consequences with the effects of L9 orthogonal array approach, the proportion error was observed to be negligible with a higher co-relation coefficient (r2) of 0.905.

Published: May 2020

Abstract
An analytical analysis has been carried out to understand the influence of dimensionless numbers in the thermal stratification of solar domestic hot water storage (SDHW) tank. Thermal stratification is the phenomena to maintain cold water layer at the bottom of the storage tank and above the cold water maintaining of hot water layer. In between cold and hot water layer one barrier layer is considered, which is called a thermocline layer. From the thermocline layer the heat transfer exchanging starts in between hot and cold water layer. The thermocline layer thickness starts increasing, which is undesired and non-beneficial from maintaining of thermal stratification of the storage tank. This degradation of thermal stratification of the storage tank cannot be eliminated fully, but only it can be reduced down somehow. Hence this analytical study analysis is about to know the influence of dimensionless numbers like Reynold’number, Nusselt number, Prandtl number on the thermal stratification of storage Tank.
