Development of Refrigeration System (Water-Lithium Bromide) Working on Solar Energy
Chandan Kumar, Sabin Mishra, Shailendra Kumar Chaurasiya
Abstract: Due to rapid depletion of fossil fuels and increasing demand day by day, the fuel prices are increasing rapidly. Environmental issues are also related with these fossil fuels. 70% to 75% house hold electricity is consumed by air conditioning system. Major part of electricity generated is contributed by thermal power plants. To address all these issues, vapour absorption refrigeration system comes in existence and has a good potential to reduce all above concerns. VARS uses low grade energy which can be obtained by sun or any exhaust energy which is going to be waste. The main objective of this work is to minimize the electricity consumption and protect environment. In thisPaper , development of vapour absorption system is presented. It is a two fluid system comprising of water& Lithium Bromide. Instead of a compressor it uses solar energy to run a generator, as opposed to a standard refrigerator. A low grade heat source heats up the absorber-absorbent pair releasing the refrigerant in vapour form. This vapour is air cooled to liquid state at the condenser. Finally hydrogen reduces the vapour pressure of the ammonia liquid entering the evaporator causing the liquid to boil absorbing heat from the cabin and in turn cooling it. The running cost will be negligible and it is eco-friendly also. Design and fabrication of Lithium bromide-water vapour absorption system of 0.5TR is presented. Solar energy will be supplied to system through Solar panel. Other major components of this system are generator, Absorber, Condenser, evaporator and pump. Such system may be used for food preservation and air-conditioning of offices, Schools, where people are in the day only. Keywords: Solar energy, LiBr-H2O, VARS, Eco-friendly, Low running Cost.

Processing of Syntactic Foams: A Review
Ankur Bisht, Brijesh Gangil
Abstract: For structural application different types of lighter material with higher specific strength are being developed now days like honeycomb, metal foam, sandwich panels, syntactic foam etc. In this review paper the syntactic foam is discussed among all these lighter material. Syntactic foams are the materials in which micro spheres are incorporated in a matrix. In syntactic foams, the matrix is reinforced with hollow spherical particles which have a controlled systematic arrangement in the matrix. Hollow microspheres give the syntactic foam its low density, high specific strength, and low moisture absorption. Microspheres may comprise glass, polymer, carbon and ceramic or even metal. The strength of syntactic foams can be nearly equal to that of the matrix. The plateau and yield stress can be tailored over a wide range by selecting appropriate volume fraction and particle type. Metal matrix syntactic foams are expected to have better properties compared to open or closed-cell metallic foams since the former have controlled size and geometry of porosity and the ceramic shells contribute to stiffness and strength. Several preparation methods are used for preparing syntactic foam and various applications are discussed, depending on the types of matrix and reinforcement used. Keywords: Microspheres, Metal foam, Composite, Mold.

Strength Analysis of Fly Ash Replacement in High Alumina Cement
L. Raj, S.S. Pradhan
Abstract: The rising cost of construction materials in developing countries has necessitated research into the use of alternative materials in civil engineering construction. Concrete mix design is a process of proportioning the ingredients in right proportions. Though it is based on sound technical principles and heuristics, the entire process is not in the realm of science and precise mathematical calculations. This is because of impreciseness, vagueness, approximations and tolerances involved. In this study concrete mix of M35 was used as control, while fly ash was used to replace high alumina cement by volume. Eighty cubes ere produced and the weight and compressive strengths were evaluated at 1st day, 3rd days, 7th days, 14th days and 28th days. This paper also presents the development of a novel technique for approximate proportioning of standard concrete mixes as suggested in IS: 10262-2003 and IS456-2000. The results in terms of quantities of cement, fine aggregate, course aggregate, water and fly ash obtained through the present method for various grades of standard concrete mixes are in good agreement with those obtained by the prevalent conventional method. Details of the system model are described and comparative graphs are presented. Keywords: Concrete Mix Design, Compressive strength, Fly ash (FA), High alumina cement (HAC).

Puneet Sharma, Ashish Gupta, Anuj Kumar Jain, Vikas Rastogi
Abstract: The study of vibration plays a significant role in many engineering problem. Free vibration analysis of a continuous beam with free-free boundary condition is carried out in this work Free-free end condition is generally encountered during operating condition of aeroplanes, missiles, submarine etc. where the structure is not supported at the both ends as such they are floating in space. Two significant parameters associated with a vibrating body are natural frequency and mode shape. In this work, the mathematical model of a beam is developed with the help of Euler- Bernoulli beam theory, which depicts the natural frequency of the beam and associated mode shape of the beam. FEM model of the beam has been created and simulation work is carried out on ANSYS 15.0 software. Moreover, experimental analysis is also performed through OROS software. Results obtained through mathematical model are further compared with experimental model and computational model, which provide a considerable agreement with each other. Keywords: Free-Free beam, FEA, Ansys, OROS.

Energy and Exergy Analysis of Trendsetting Internal Combustion Engine: A Review
Pushpendra Upadhyay, Brajesh Tripathi
Abstract: Demand for higher fuel economy and lower exhaust emission of combustion ignition engine need to be achieved either by reducing exergy loss or blending diesel with bio-fuel to reduce pollutant emission from transportation sector and meet satisfactory engine performance which is major technical challenge since the world is confronted with energy scarcity. Computational model of TDC was investigated to get energy and exergy distribution for different trendsetting internal combustion engine. The result indicated that the 50% heat release point (CA50) considerably affect fuel efficiency and ringing intensity. Heat transfer loss of CDC depends on temperature gradient, in case of homogeneous charge compression ignition (HCCI) and reactivity controlled compression ignition (RCCI) it depends on heat transfer area. Exergy destruction is related to different factor, temperature inside cylinder, air fuel ratio, chemical reaction rate, combustion duration and temperature. Considering these factor conventional diesel combustion (CDC) engine shows high exergy destruction compared to HCCI and RCCI. Overall change in exergy distribution obtained from second law of thermodynamic for three different combustion strategy are consistent with those obtained from first law of thermodynamic. HCCI shows the highest energy and exergy efficiency and CDC performs the worst. Keywords: HCCI Homogeneous Charge Combustion Ignition, RCCI Reactivity Controlled Combustion, Ignition, CDC Conventional Diesel Combustion.

Mohd. Yunus Khan, Praveen Pachauri, Atishey Mittal
Abstract: Diesel engines play very vital role in the different sectors like transportation, industrial and agricultural. Depletion of fossil fuel reserves and increased environmental degradation has generated interest in the use of alternative fuels. Vegetable oils are found to be most promising alternative fuels. Since they are renewable fuels, biodegradable, non-toxic and eco-friendly. Above all, they operate in conventional engine just like diesel thereby requires no major engine modifications. In this experimental investigation, potential of blend of 10% sesame oil and 90% diesel as alternative fuel has been evaluated. Engine performance and emission characteristics obtained with this blend is compared with that obtained with pure diesel. But before that, important properties of sesame oil in comparison to diesel were discussed. When blend of sesame oil-diesel is used, slightly higher fuel consumption rate and lower brake thermal efficiency were obtained. Also, lower air-fuel ratio and higher exhaust gas temperature were obtained with blend of sesame oil-diesel. NOx and CO emissions of the engine were found to increase slightly when sesame oil-diesel blend was used. From this experimental investigation, it has been established that sesame oil-diesel can be substituted for diesel as fuel diesel engine without any engine modification. Keywords: aternative fuel, vegetable oil, sesame oil, blend, performance and emission characteristics.
