Abstract

When the subjects for Engineering curriculum were thought of and designed, importance to the “power of imagination” was given preference. This requirement gave birth to the subject “Engineering Drawing”. Over a period of time though the content underwent modifications, the basic ideas/requirements were retained. With the introduction of super specialties in engineering specializations, new subjects were introduced in the place of existing ones, as latest inventions were to find place in the curriculum. However, the subject Engineering Drawing could not be touched/replaced because of its importance to the engineer.

Abstract

Ultrasonic vibrations have various kinds of applications in machining operations. A large number of researchers have been involved in the investigation of ultrasonic effects in conventional machining operations. In most of the cases, they have obtained favorable effects. In this regard, this paper discusses the effects of ultrasonic vibrations, especially in EDM processes. The mechanisms which are helpful in improving the material removal include, cavitation, micro-streaming and impact forces by ultrasonic waves. One of the major challenges in EDM is to improve the sparking and flushing efficiency, which is critical in processes such as micro-EDM. Generally, it is understood that ultrasonic vibrations reduce thermal damage of the surfaces generated in EDM. Two ultrasonic parameters influencing the processes are ultrasonic amplitude and frequency of ultrasonic vibration. Several researchers have done mathematical modeling of the effects of ultrasonic vibrations in EDM. It helps in the prediction of key factors influencing the process, such as ultrasonic force required for debris evacuation and debris concentration at the inter-electrode gap.

Abstract

Analysis of surface roughness and Material Removal Rate play vital roles in machining Austenitic steels. Austenitic stainless steels have high ductility, low yield stress and relatively high ultimate tensile strength, when compared to typical carbon steel. In the present work, prediction of surface roughness and material removal rate in milling of AISI 304 stainless steel is carried out using fuzzy logic. 27 experiments based on Taguchi's L orthogonal array were carried out 27 involving three machining parameters namely, cutting speed, feed rate and depth of cut, each defined at three levels. Subsequently, the prediction model was developed using triangular fuzzy logic membership function. It is found that the predicted values of proposed responses such as surface roughness and Material Removal Rate are very close to the experimental values within the chosen ranges of the process parameters. The statistical analysis using ANOVA on machining parameters are also presented and discussed.

Abstract

The analysis of commercially available piezoelectric coefficient of mono-crystalline materials such as PMN-PT (Lead Magnesium Niobate - Lead Titanate) helps to broaden the gate for silicon-integrated applications (Piezo-MEMS) becoming more compatible with micro technology batch processes. Further, advances are expected in terms of miniaturization, optimization, functionality or integration with electronics. Subsequently, operating voltage will be lower and devices response time will improve dramatically. Fabrications of the piezoelectric materials have been performed and analysis on the structure and dielectric has been carried out. This work shows how to improve the dielectric properties for synthesis material.

Abstract

Experiments have been conducted on square duct to investigate natural convection heat transfer from the outer surface of axially horizontal square ducts. Steady State Heat Transfer characteristics are studied under laminar and transition regions. Constant heat flux heating element is used to heat the duct from the center and 10 equidistant points are located on each side of the duct to measure temperature from all the four sides using IR-Thermometer. Correlations were developed in the form of circumferential averaged Nusselt number, modified Rayleigh number.

Abstract

The vapour-absorption refrigeration cycle is a traditional and well-established technique, particularly with ammonia/water and water/LiBr (Lithium Bromide). Energy management has further enhanced its possibilities in day-today applications. Modifications have been suggested in compression–absorption refrigeration system which offers numerous advantages compared to conventional absorption systems. A detailed thermodynamic analysis and parametric study of NH -H O based compression absorption system has been carried out with an objective to get an 3 2 insight into the performance and feasibility of this system under varying operating conditions. The operating parameters studied are the effects of concentration of weak solution leaving the desorber on COP and variation of saturation pressure with respect to concentration keeping in view certain assumptions.
