Volumetric Efficiency of Four-Stroke Diesel Engine Using Jamun Seed Methyl Ester Oil (JSMEO) with Varied Piston Configurations and Injection Pressures
Subbarao B, Ramjee E and M V S M Krishna

Non-edible crops are being grown exclusively for biodiesel production. An alternative approach is to grow a food crop and use the waste material for biodiesel. Crude Jamun Seed Oil (CJSO) is unrefined non-edible vegetable oil, which is available in dry land countries. The research in this area to utilize CJSO as a replacement for mineral diesel is very less. CJSO is obtained from solvent extraction process using n-hexane. The transesterification process for production of Jamun Seed Methyl Ester Oil (JSMEO) has been investigated. The production of high quality JSMEO is obtained from the transesterification with methanol and KOH as a catalyst convertor. Single cylinder four-stroke water-cooled direct injection diesel engine is used in the test rig. JSMEO is used to determine the performance characteristic of the engine. Experiments have been carried out using piston head geometry at constant speed.

Performance Analysis of Solar Water Heater Using U-Shaped Heat Pipe
Sunil Nain and Pinku Kumar

The paper fabricates and experimentally analyzes solar water heater fitted with evacuated tube and U-shaped heat pipe. The arrangement comprises 10 evacuated tubes and U-shaped copper heat pipe inserted in the evacuated tubes to advance the performance of the solar water heater. A U-shaped copper heat pipe is utilized to exploit natural circulation of heat and ethylene glycol is used as base fluid. The framework execution is estimated as far as change of temperature, net heat gain by water and efficiency of the solar water heater. The exhibition parameters are plotted against various estimations of ambient air temperature, outlet water temperature and solar radiation intensity for different mass flow rates. The maximum temperature achieved at fixed quantity of water (100 L) is 78.8 C using heat pipe and 59 C without heat pipe. The maximum increase in change of temperature of water is 15.38% using heat pipe in 90 min at low flow rate of water (0.01639 kg/s). The maximum value of net heat gain at 0.03225 kg/s flow rate of water in the trial period is 715.66 J/s and corresponding efficiency of solar water heater is 68.95% using heat pipe, whereas maximum value of net heat gain is 580.63 J/s and corresponding efficiency is 56.66% without heat pipe. The maximum percentage increase in net heat gain using heat pipe is 23.26% as compared to simple system with high mass flow rate of water (0.03625 kg/s). The increase in the efficiency of solar water heater using heat pipe is 21.69% as compared to simple evacuated tube-based system with high flow rate of water (0.03625 kg/s).

Parametric Optimization of End Milling Operation on EN24 Steel Shaft of Grinding Machine
Kishan Vaghamshi and G D Acharya

The milling of EN24 hardened steel has been applied in many cases in production. The paper investigates the influence of milling operation parameters (cutting speed, feed and depth of cut) on the Material Removal Rate (MRR) and surface finish in milling of EN24 steel. The effect of milling operation parameters is evaluated for minimum Surface Roughness (Ra) and maximum MRR using Taguchi design methodology. EN24 grinding wheel steel shaft is a machined component mounted on grinding machine. Maximum MRR with high surface finish in machining is highly desirable for EN24 steel shaft. The research model can be effectively used to predict Ra and MRR in milling of EN24 steel.

Friction Stir Welding in Al Alloys: A Study
Harvinder Singh, Santosh Kumar and Rakesh Kumar

Friction Stir Welding (FSW) is a solid-state fabricating method used to produce superior quality welds with lesser defects. This process, generally performed at the melting temperature, utilizes non-consumable tool to develop frictional heat in the adjoining surfaces, and the base metal that is being joined does not melt. FSW is capable of fabricating Cu alloys, Ti alloys, Al alloys, Mg alloys, stainless steel and mild steel. In recent times, it was strongly utilized in welding of polymers. Further more, this process is used for fabrication of dissimilar materials, including Al to Mg alloys. The main benefits of FSW are: very low weld cost, superior tensile strength, low distortion, high microhardness, refined microstructure, produce defect free joint and environment-friendly. These reasons make the welding process highly suitable for distinct industrial applications (railway, shipbuilding, aerospace, Al industries, etc.). However, the weld quality and strength of FSW joints are also affected by tool pin profile. Hence, the paper reviews the FSW process, classifications, applications, process variables and the effect of distinct tool pin profiles on the mechanical properties of FSW Al alloys.
