 Abstract

In the modern era, almost every learner would have come across the word E-learning and every part of education and training system enthusiastically explores and implements E-learning in one form or another. E-learning is a broad concept. It refers to a wide range of techniques and methods. It is often employed as a unifying term to describe the fields of online learning, web-based teaching and technology delivered instruction. With the amazing development of Internet, the field of education has tried to exploit web as a communication channel to connect distant learners with their learning resources. E-learning creates awareness in modern education and it offers a greater degree of freedom in Teaching Learning Process (TLP). E-learning activities are important for the development of any country on this globalised globe when in modern era everybody is thinking about growth and Educational development. In this research paper the up-to-date developments through E-learning in India is observed with the objective to comprehend the rapid popularity, the concept of e-learning is gaining as well as its possibility to be the focal wheel of development of education sector of India in near future.

 Abstract

This paper boarder around design, fabrication and testing of a remote controlled airplane with high payload ratio. In the field of aviation, engineers play a vital role in solving complex problems like producing an airplane with high payload ratio, aerodynamic & performance efficiencies and structural safety. However, some of these problem statements are reduced in scale and given to engineering graduates for innovative results and applications. One such society which bridges this gap between industrial engineers and engineering graduates is the Society of Automotive Engineers (SAE). Two members of our project team have already registered for SAE Aero Design Competition 2018 which is going to held in California during April, 2018. The purpose of this project is the gradation of visionary design, manufacturing, system integration and experimentation of a remote controlled airplane with high payload ratio capable of lifting great loads while remaining as light as possible. An optimal design will be developed by maximizing the aerodynamic lift and reducing the aircraft weight without compromising the overall performance. However, the design must stay within the rules and restrictions of the SAE Aero Competition Guidelines

 Abstract

The design of a can combustion chamber in a gas turbine engine is the backbone of this paper. It is specifically designed for a low bypass turbofan engine in a jet aircraft. The combustion chamber is positioned in between the compressor and turbine. It has to been designed based on the pressure, enthalpy addition process. The present methodology deals with the increasing efficiency of jet engine by using Micro turbine. Basically micro turbine is used for producing energy in aircraft engine, by controlling the sensors processing energy scavenging. The combustion chamber result is calculated with micro turbine and without micro turbine. To comparedthe result for final flow of some parameters like the pressure, velocity and temperature. The whole combustion chamber is modeled using CATIA V5R20, the modeling software and presented. The model is then analyzed using various parameters at various stages and levels to determine the optimized design. The aerodynamics flow characteristics are simulated numerically by mean of ANSYS 14.0 software suite. The air fuel mixture, combustion turbulence, thermal and cooling analysis is carried out. The analysis is performed at combustion chamber flow output then compared them with micro turbine and without micro turbine.

 Abstract

Using diesel engines mostly as main power source has gained the importance in the recent years. Technical specification of the diesel engine and its components has been the main focus of the researchers. The muffler is defined as a device for reducing the amount of noise emitted by an engine. The muffler is engineered as an acoustic sound proofing device designed to reduce the loudness of the sound pressure created by the engine by way of Acoustic quieting. Due to increased environmental concerns requiring less noise emissions combined with reduced emission of harmful gases, it is becoming very crucial to carefully design the exhaust system mufflers for road transport applications.In this Study comprehensively two different models of exhaust mufflers viz., reactive muffler and resonative mufflers are comprehensively analyzed to determine the best possible design for least pressure drop. Back pressure will be obtained based on the flow field analysis and compared with other muffler designs. Virtual simulation for back-pressure testing is performed by Computational Fluid Dynamic (CFD) analysis using Ansys CFD. Finite Element (FE) Model generation of the muffler structure is performed using Hyper Mesh as the preprocessor. The structural mesh is modeled using 2D shell elements, where in the internal tubes with fine perforated holes are considered. The CFD fluid meshing has been done with tetra elements using Ansys as the CFD preprocessor. As a result the back pressure generated across the muffler is determined by measuring and inputting the mass flow rate of the exhaust gases entering the muffler inlet pipe. Field view is used for post processing the CFD results and reviewing the airflow streamlines. The exhaust gas velocity and pressure plots are plotted across the internal tubes and perforated holes, and hence the back pressure is measured.

 Abstract

The overall objective of this study is to find an alternative solution for the large volume of sludge produced in the wastewater treatment plants . The generated quantities of sludge are expected to be 55.74 tons of solid per day by the year 2025. This large quantity of sludge is related to the scarcely of land area and high population density represented the sludge problem. Many researchers worldwide have been trying to explore new and suitable solutions to solve part of sludge problem. One track of these solutions is to use sewage sludge in construction field. The current study presents the usage of dry sewage sludge in the concrete mixtures and in manufacturing interlock brick samples. According to results findings, no significant strength loss was observed when low organic sludge was used in making concrete cube specimens. The strength loss was increased to 17% when 10% of high organic sludge pellets by cement weight was added to concrete mixture. The results showed that the dry sludge retarded the strength development and has more adverse effect on compressive strength when it has higher organic content and its particles became finer. The addition of dry sludge to interlock brick paste produced a reduction in compressive strength by only 12%. The presence of sludge in interlock samples decreased its density and increased its absorption coefficient. The NEN 7345 leaching test results indicated that the concrete matrix could be fixed more than 73% of total organic material in the worst case. Finally the study concluded that the dry sludge can be used in as an additive to concrete mixtures and to interlock brick paste as one of the available disposal options for sludge. The study recommended that more researches are needed to evaluate the durability of sludge concrete and the behavior of reinforced sludge concrete
