 Abstract

ABSTRACT Today, Gas turbines are one of the most widely used for air craft propulsion, land based power generation and industrial applications. The temperature at which the turbine operates (firing temperature) also impacts efficiency, with higher temperature leading to higher efficiency. However, inlet temperature of a turbine is limited by the thermal conditions that can be accepted by the turbine blade metal alloy. Gas temperatures at the turbine can be 1200C to 1400C but some manufactures have boosted inlet temperature as high 1600C by engineering blade coatings and cooling systems to protect metallurgical components from thermal damage. In the present work to examine the heat transfer analysis of gas turbine with different models consisting of blade with varying number of holes (5,9&13) were analyzed to find out the optimum number of cooling holes. The analysis is carried out using commercial CFD software FLUENT (a turbulence realizable k-? model with enhanced wall treatment) has been used. Steady state structural analysis is carried out using ANSYS software with different blade materials of chromium steel and Titanium Alloy.

 Abstract

The design and development of composite pressure vessels are driven by the need for minimum weight. Design, analysis, and optimization complexities are compromised due to constraints of computational resources and shorter cycle time. Advanced lightweight laminated composites are increasingly being used in modern Aerospace structures, for enhancing their structural efficiency and performance. One of the most common failure modes for composite structures is delamination. The remote loading applied to the composite components are typically resolved into interlaminar tension and shear stresses at discontinuities that create a mixed mode I, mode II and mode III delaminations. In this study, we focused on the former option by keeping the ply sequence constant and varying the associated ply angle. For the case of un-cracked shell, the cylindrical shell with the composite ply angle of 30 leads to maximum load capacity against buckling load. In addition, the effect of crack length and orientation on the buckling behavior of composite cylindrical shells comprising a through crack is studied, using a special meshing scheme and providing the inter205 element. Based on the fracture analysis and calculated the crack growth (7.5 TON) and failure load (10.5 TON) based on power law Cylinder were tested up to 7.5 TON and LVDTs removed. The cylinder failure load is 11.2 TON against a failure strain in carbon fabric/ epoxy composite is 3200-3500 micro-strains. They show good agreement at all the regions. However, the result finite element analysis shows close agreement with the experimental results. Also, the design stresses were within safe limits. Radial displacement as per FEA is 0.8mm and experimental value is 0.6mm at 7.5 Ton load. For the case of un-cracked cylindrical shell with the composite ply angle of 30 leads to maximum buckling capability. Investigation was carried out on the composite cylinder with delamination, when cylinder was subjected to compressive load. The strain energy release rate is increase in mode-2 leads to reducing the buckling factor was observed.

 Abstract

This Paper accommodate a case study on Protection of generator and Generator relay installed at Eklahare, NTPS that recognizes faults in 210MW unit and prevent them from unnecessary tripping. An electrical protection system design is most important to ensure reliable and efficient operation in thermal power plant. The paper describes various generator protections working under respective protections classes set at NTPS on the basis of tripping. Differential protection of generator, stator inter turn protection, stator earth fault protection, loss of excitation, generator under and over frequency protection have been explained in details.

 Abstract

In medicine, adherence (also capacitance) describes the degree to which a patient correctly follows medical advice. The m-health is defined as a wireless telemedicine involving the use of mobile telecommunications and multimedia technologies and their integration with mobile healthcare delivery systems. In this paper we are developing the m-health application which is Android-based reminder application, it addresses the common healthcare issue such as attending appointment and taking medication on a proper schedule as prescribed. The m -health application also has an option of entering data in a quick and easy manner by using the chosen automated data-entry technology, the Quick Response (QR) code.

 Abstract

In most Indian cities or towns, the urban poor survive by working in the informal sector. Poverty and lack of gainful employment in the rural areas drive large numbers of people to cities/towns for work and livelihood. As permanent protected jobs in the organized sector are shrinking so working in the informal sector are the only means for their survival. This has led to rapid growth of the informal sector in most of the cities of India. For these poor, street vending is one of the means of earning a livelihood. In recent years Assam has been experiencing substantial increase in the number of street vendors. The paper has made an attempt to examine the socio-economic and work related conditions of the street food vendors of Sonitpur District of Assam. It has also highlighted some of the policies and the organizations that have been developed for the protection of these vendors.

 Abstract

Radio is a cheap, portable, accessible and universal medium that gives Infotainment (information & entertainment) to the masses, almost free of cost. Developments in the field and evolutions in the technology from AM, FM to Satellite and Internet Radio have made a huge impact on the Radio Industry in India. Radio offers different services catering to the different regions and people of India. All India Radio or Akashvani is the national broadcaster, a constituent of Prasar Bharati (Broadcasting Corporation of India) within the Ministry of Information and Broadcasting. Since its beginning, radio has been growing at a steady speed and it is now the second fastest growing sector after the Internet in India. The radio industry has managed its growth by increasing the advertising list, not by increasing prices of the sets. Private FM radio in India is growing at a challenging 14.5%, primarily due to FM expansion in Tier 2 and Tier 3 cities. Although the ad-pie continues to be only 4%, it is hoped that it will grow to 7% in India by 2020.

 Abstract

Emerging Wireless Sensor Networks-Cloud Computing based networks will offer substantive choice in delivery and opportunities for building better system. Wireless sensor network is the domain of embedded system that can sense the objects, capture the detail and forward to the next hop. Cloud computing is another technology that gives seamless service to the operator and customers. It is application oriented network and designed for small scale to Enterprise networks. This research based proposal is intent to collaborate the inter-domain non-diversity networks that guides planned actions. The objective of the research work is to reduce the power consumption from the desired path as a function of Load Balancing. It is observed in many cases, change of multi-domain would impact the connectivity; Load balancing algorithm is the solution to a problem and sending the updated path to the parental node in the network. The proposed algorithm has supported capabilities to offload traffic to the cloud systems. In this heterogeneous system taken together related to business corporations and Load Balancing Algorithm is applied for managing this system which are separated from preconception like interference, power consumption and high latency in the system. This system resolve problem and decomposing the sensor networks into cloud based environment. This proposed system can not only making the sensor networks more friendly but also improve power consumption and is used in mission critical applications.
