Title | : | Automation of Media Filter |
Country | : | India |
Authors | : | Anshuman Kulkarni¹, Sunil Yadav, Abhishek Mahajan, Pravin Khachane |
Abstract: Media Filters are primarily used to separate suspended particles, river silt and other impurities from the water. It is used in Irrigation and in Sewage water treatment. It has a robust fabrication with quality and precision. Media Filters provide a fixed material on which a thin biological film is established by organisms in colonies growing on the surface of the media as wastewater passes through the bed. These filters are used for fine sifting the water. These filters are capable of handling high volume of flow up to 60,000 lit per hour. However they can be connected with help of header assemblies for more volume of flow. So the need arises to control their operation automatically with the help of advance in technology. Backwash operation is manual for the filter. We propose to use Pressure transmitter, electrically operated valves, Microcontroller and timer for the operation for backwash operation. Pressure transmitters are used for two pressure input at inlet and outlet. By setting a microcontroller we can measure ΔP. If the value of ΔP is larger than specified value of designer, then a sequence of valves operate backwash mechanism. In backwashing of a filter the flow of water is reversed in opposite direction.
Keywords— Media Filter Backwash, Irrigation, Automation, Microcontroller.

Abstract: Solar energy is becoming one of the important energy in the future as a great renewable energy source. Solar cells vary its performance under temperature changes. Change in temperature affects the power. The rapid development of solar PV cells has created challenging environment in the future. However the cost of electricity from solar PV cells is still several times higher than the conventional power generation. So it is very necessary to improve the efficiency of the solar PV cells. Efficiency can be increased either by changing PV material, concentrating solar rays or using solar tracking system. There are various methods for concentrating solar rays. In this study we used optimised angled collector for concentration and manual Bi-axial Sun tracking system. It is found that by using Collector of optimized size and biaxial tilting of the panel, performance of the PV cell panel is increase tremendously.

Title | : | Natural Fiber Reinforced Composite in Energy Absorption Structures |
Country | : | India |
Authors | : | Gowtham N, Azad A |
Abstract: Composite materials along with the thermoplastic matrices and with the reinforcement of natural fibers are increasingly regarded as alternative for glass fiber-reinforcement composites. Natural fiber reinforced composite provides some unique advantages for the customers, it includes less weight, bio degradable, and it has very good thermo physical properties. The traditionally used reinforcing glass fibers is replaced by natural fibers such as flax, kenaf, cotton or banana fiber. It can lead to the reduction in components weight and it improves specific properties like impact strength, crash behavior or sound absorption. Poor incompatibility between the hydrophilic natural fiber and non-polar polymers leads to negative effect. A variety of silanes have been applied in order to improve its interfacial adhesion and improve the properties of composite. The NaOH concentration had a major influence on the thermo physical properties of the composite. This work is focused on the impact energy absorption structures includes helmet, car bumpers etc., by using High Impact Polystyrene as matrix and Banana fiber as a reinforcement.

Title | : | Design Modification and Analysis of Rotavator Blade. |
Country | : | India |
Authors | : | Jeevarathinam.A, Velmuruga |
Abstract: The computer aided engineering analysis and design optimization of rotary tillage tool on the basis of finite element method and simulation method is done by using CAD-software for the structural analysis. In Indian farming, the preparation of seedbeds for deep tillage using additional machinery and tillage tools are increased. Rotary tiller or rotavator is one of the tilling machine most suitable for seedbed preparation. In a Rotary tillage machine, Blades are the critical parts which are engaged with soil to prepare the land and to mix the fertilizer. These blades interact with soil in a different way than normal plows which are subjected to impact that creates cyclic forces which result in fatigue failure of the blade. This actually decreases the service life of a blade. Therefore, it is necessary to design and develop a suitable blade. This paper describes the design modification and development of rotavator blade through the (CAD) interrogation method by modifying the design and also by modifying the material properties. Then better design will be compared by comparing the results.

Title | : | Rejection reduction of Vacuum Pump type Alternator Assembly |
Country | : | India |
Authors | : | B. Shanmugam, Dr. K. Kalaichelvan |
Abstract: Conventional manufacturing thought limits the rejection reduction plans to rejections which needs to be scrapped and implies direct loss. But present scenario in manufacturing industries, which is facing a very competitive environment, needs to consider not only rejections leading to scrap but also rejections which can be reworked or reused. Rejections which leads to rework results in man-hour losses which in turn affects the productivity of the organization. This paper focuses on assembly rejections of vacuum pump type alternators. Top of the Pareto is a rejection called "Pump rotation tight" which accounts to 50% of total assembly line rejection of vacuum pump type alternators. In order to reduce the rejection & rework, a study is conducted to analyze the rejection using appropriate statistical tools, Shainin technique for assembly process which indicated that two of the sub assembly components were the root cause for the rejection and subsequently optimize the subassembly shaft spline runout which is manufactured by cold rolling process using Taguchi Orthogonal array. Application of these tools helped in improving the knowledge base of the manufacturing and assembly process and also helped narrowing down to the root cause or a number of root causes in quick span of time.

Abstract: The very fast developments in technology of composite materials have led to newer and wider applications of such promising materials. Composite materials offer a number of potential advantages in the aerospace field, particularly in safety-critical structures such as primary and secondary aircraft components. Here Basalt Fiber as a reinforcement and Epoxy (Di-Ethylene Glycidel Ether BisPhenol-A) as a matrix for making a Composite Material have been chosen. Basalt provides high strength than the commercial Glass fiber. It provides high heat resistance. Since this material is having a great Scope in Space application it has been choosen for determining Mechanical characterisation of this materials. Tensile Test , Bending Test have been carried out for this purpose. Specimens have been preferred with and without addition of Aluminium with Epoxy. The results are compared and it has been studied that Aluminium increases the strength of the specimens in the above mentioned tests.
