Process Average Temperature and Simple Thermodynamic Diagram for Real Vapor Absorption Refrigeration System
Sanjay Khatwani and Govind Maheshwari

The paper summarizes the thermodynamic performance of an irreversible singlestage Vapor Absorption Refrigeration (VAR) system with water-LiBr pair as a simple rectangular temperature-entropy diagram, analogous to ideal reversible systems. In this graphical framework, a reference temperature, termed as process average temperature ( Tpav ), is taken as a significant conversion factor for translating intricate dissipative losses into lost work. Tpav can also be understood as the temperature of the refrigerant, in which the process may be assumed to be an equivalent isothermal process for the purpose of calculating entropy changes. A simple thermodynamic model is used to represent the principal energy and entropy transfers and their influence on the performance of VAR system in terms of the relative areas of the various rectangles. Actual data from commercial steam-fired VAR system is used to explain the easily-interpreted graph and to highlight the dominance of internal dissipation in determining the performance of absorption systems. With the Tpav -entropy diagram, various components of irreversibility and the reversible and endoreversible limits become apparent.

Measurement and Control of Axial Misalignment in Connecting Rod Manufacturing of Compression Ignition Engine
S S Sonigra

The connecting rod is one of the most important components of compression ignition engine. As it is subjected to alternative stresses, tensile and compressive stresses, it is designed for compressive stress as it is higher at the time of power stroke. The paper discusses two-dimensional parameters of the connecting rod in detail, i.e., bend and twist. Various methods are used in industry for measurement of these parameters. The measurement methods are discussed in detail for both the parameters. A program is prepared to assure the dimensional quality, in which the process capability indices are computed. The values of these indices represent that the process is under statistical control. The factors affecting these parameters are discussed. The parameters are identified to control axial misalignment between both bores of connecting rod during manufacturing processes. The SPC analysis is conducted for these critical parameters of the connecting rod. The control charts are prepared for continuous monitoring of the process. The chart also indicates the trend of the process with the help of which the chances of rejection can be interpreted.

An Experimental Investigation on Depth of Penetration Using AR-10% H2 as a Shielding Gas in GTAW Welding of SA 240 TP 304H
Ashish Pandya, Manojkumar V Sheladiya and Ghanshyam D Acharya

The fabrication industries are facing problems in weld penetration using only argon as a shielding gas for square-butt weld joint design. The paper investigates the effect on depth of penetration with a use of 10% hydrogen as balanced shielding gas with argon. Welding current, welding speed and gas flow rate are selected as welding parameters to summarize the effect of hydrogen on the depth of penetration. The study was carried out on square-butt welding on autogenous Tungsten Inert Gas (TIG) with nonconsumable electrode without filler wire. Major interest has been shown in arc power, arc efficiency and the statistic characteristics of a welding arc. The resulting input process parameters were optimized with the use of response surface optimization technique.

Optimization of Process Parameters in Friction Stir Welding of Aluminum Alloys (AA6082 and AA6105) by Taguchi Technique
Sourabh Rohilla, Upender Dhull and Ravinder Chaudhary

Friction Stir Welding (FSW) of dissimilar alloys (Singh, 2018) is very important in structural, automotive and aerospace application and needs attention. It substitutes the conventional welding technique very well. The paper focuses on the FSW of wrought AA6082 and AA6105 that are highly used in structural and automotive industries (Dhananjayulu, 2017) and aims at finding the effect of process parameters on the mechanical properties of the FSW of aluminum AA6082 and AA6105. Aluminum AA6082 and AA6105 plates of 5 mm thickness are used. A systematic study has been performed on the weld area and the process parameters optimized. Minitab17 software was used to analyze the Taguchi technique. Nine samples were welded on a vertical milling machine by varying the values of three process parameters. The process parameters considered were rotation speed (1,540, 2,300 and 3,080 rpm), welding speed (20, 40,60 mm/min) and tilt angle (0.5, 1.5 and 2.5°).

Adhesive Joining Process Parameter Optimization on Butt Joint with Single Strap on Shear Strength Properties of Hybrid Metal Polymer Composite Joints
Shirish Kerur and Shivakumar S

The paper examines the effect of geometric and manufacturing parameters, viz., adhesive layer thickness, surface roughness of substrates, type of resin and length of overlap on the metal sheet joints experimentally and statistically. The results showed that the length of overlapping has the maximum influence on the response parameter (shear strength), while surface roughness has the least impact. The adhesive layer thickness and type of resin have in-between effect on the shear strength of a butt joint with single strap.

Performance of Diesel Engine Using Biodiesel and Hybrid Biofuel
Madhurjya Saikia, Dilip Kr. Bora and Kalyan Kalita

Biodiesel and emulsified fuel (hybrid biofuel) are the two biomass-based fuels which have the potentiality to replace diesel in the not-so-distant future. These are renewable, nontoxic and portable fuels. Unlike biodiesel, which has been studied extensively for quite some time, not much attention has been given to the utilization of emulsified fuels and their behavior on diesel engines. In this paper, the performance of the engine has been assessed for emulsified fuel and biodiesel derived from yellow oleander seed oil in a single cylinder diesel engine, and the performance is compared with that of the diesel fuel. It is observed that Brake Specific Fuel Consumption (BSFC) for the biofuels is higher than that of the diesel. But there is no distinction between the fuels for power and torque.
