Pages: 1 - 6
In most flow applications require regulating the flow of liquid, and usually the parameter of concern is the pressure. This paper focuses on analysis of flow regulating pressure valve by Finite |Element Analysis by using nonlinear and transient finite element analysis. To control the pressure of fluid electronically or pneumatically operated valves are used. Sometime there is requirement to mechanically operated valve. Only one valve which will connect three different chambers and will control the flow between chambers by using balance stiffness based valve. The static analysis is used to determine the deformation and stresses in the valve whereas the transient analysis is used to determine the dynamic response of valve under any time dependent loads. The Transient solution was extremely useful in order to know the effects of friction and bending pressure parameters. The main purpose to design this valve is to maintain pressure inside the pressure vessel at specific level to avoid the busting of the pressure vessel. The idea behind this project is to introduce regulation by manipulating the direction of flow.

In turning many key factors like, type of tool bit and its setting angle, machining conditions, type of material to be machined, spindle speed, cutting speed and feed rate etc., plays an important role. Out of all tool bit and cutting speed plays vital role. In this study, on lathe Machine Turning operation has been carried out for different Steel materials such as Mild Steel, EN-8, EN-31 and OHNS by maintaining constant depth of cut and feed by using DNMG 110404 carbide insert tool bit and then with High speed steel (HSS) tool bit at various cutting speeds 400, 800, 1200, 1600 rpm respectively. The surface roughness values have been compared for both the tool bits and the cutting force values have been analyzed for carbide insert tool bit. From the study the effectiveness of carbide insert tool bit has been noticed for steel materials at various cutting speeds in turning operation.

Pages: 18 - 25
Concrete is most widely used construction material in the world. Fiber reinforced concrete (FRC) is a concrete in which small and discontinuous fibers are dispersed uniformly. The fibers used in FRC may be of different materials like steel, G.I., carbon, glass, Aramid, asbestos, polypropylene, jute etc. The addition of these fibers into concrete mass can dramatically increase the compressive strength, tensile strength, flexural strength and impact strength of concrete. In this study the results of strength properties of steel, glass, and polypropylene fiber reinforced concrete have been presented the compressive strength of concrete samples made with different fiber amounts varies from 0%, 0.25%, 0.5%, and 1% were studied. The samples with the addition of the different fibers showed better results with increase of fiber content.

Pages: 26 - 31
Abrasive water jet machining, one of the non-traditional processes for machining and cutting uses the abrasive particles mixed with the water jet and is impinged onto the workpiece for manufacturing processes. In this study focus is on the investigation of experimental work based on Taguchi method for machining of granite material with abrasive water jet machine. Three control factors were selected - Traverse speed (mm/min), Water pressure (MPa) and Stand-off distance (mm) with two response parameters – Material removal rate (gm/min) and Surface roughness (ð›m). With the help of ANOVA (Analysis of variance), it was observed that traverse speed was the most significant parameter affecting Material removal rate (MRR), while Stand-off distance (SOD) was found to be the most significantly affecting factor for the surface roughness parameter. It was also observed that with increase in traverse speed, MRR and surface increases. A multiple linear regression model was also developed for prediction of results.

Behaviour Analysis of High Volume Fly Ash Concrete

Year: 2016, Volume:3, Issue : 5
Pages: 32 - 35
Now a day’s concrete pavements are gaining popularity for its own good paving properties, as such consumption of cement is increased drastically. As cement demand increases, production also increases. Every ton of production of cement releases approximately 7% carbon dioxide to environment. In many industries, including power plants, coal is used as fuel. This generates tonnes of coal ash, which is very difficult to dispose off, which in turn causes pollution. Thus the production of cement and electricity contributes huge amount of carbon dioxide emissions and coal ash causing environmental pollution. The present study aims at developing a concrete by replacement of Ordinary Portland Cement (OPC) Up to 50% Fly Ash by mass. The fresh and hardened properties of High Volume Fly Ash Concrete (HVFAC) with 50% replacement of cement and Ordinary Portland Cement Concrete (OPCC) are studied. The study discloses that high volume of Fly Ash in concrete reduces the water demand and improves the workability. Study also reveals that OPCC and HVFAC exhibit similar hardened properties. Comparison of flexural response of beams made with OPCC and HVFAC with different percentage of reinforcement are also studied. It is observed that HVFAC beams have shown notable improvement in the deflection, cracking behaviour and load carrying capacity.

Pages: 36 - 39
Solar energy is the most important renewable source of energy. The demand of Photovoltaic system is due to the fact that they produce electric power without hampering the environment. Solar PV modules directly convert solar energy into electrical energy. Solar energy is clean and completely natural energy. By using the Solar Tracking System solar module able to maintain the position that sun’s rays are always perpendicular to it. Solar Tracking system increases the output from of solar module. This paper reviews the progressive development of the technology used for solar tracking system. This paper also tries to emphasize the various practices and methods to promote the benefits of solar tracker and also discusses other techniques to increases the efficiency of solar module.

Year: 2016, Volume:3, Issue : 5
Pages: 40 - 45
India, located in South Asia is a large country that ranks second in the world in terms of population and seventh in terms of geographical area. But, India greatly lagged behind economically and socially compared to the developed world one factor which is a drag on its development is the lack of world class infrastructure. As the development of world class infrastructure in tune with the growing needs and also for strengthening and supplementing the existing infrastructure facilities is a herculean task for governments alone especially due to fiscal constraints and other monitory liabilities, Public Private Partnership (PPP) model has emerged and is likely to be encouraged as a preferred mode of funding infrastructure. Though India adopted the mixed economy approach of economic development, the said principle of public-private partnership is still vague in its conception, actual adoption and implementation. The PPP projects are widely implemented in the areas of infrastructure services such as education, health care, transportation, tourism, energy and Urban Development. The objective of this paper is to examine the relevance of the PPP projects implemented in India, their progress and future potential. The study relies on secondary information published by the Department of Economic Affairs, Ministry of Finance, and Government of India. The study highlights the regional disparity in the PPP Projects across Indian states. There is need to focus on social sectors, especially health, education and agriculture which currently accounts very small number of PPP projects in India.
