TRANSFORMER PRO TECTION USING NUMERICAL RELAY
PROJECT REPORT
Submitted by
AMBILY G ASHA V N SHYAMA K
INTRODUCTION
The aim of this project is to analyze and upgrade existing transformer protection system in BPCL Kochi Refinery. Transformers are static devices totally enclosed and generally oil immersed. Therefore, chances of faults occurring on them are very rare. However the consequences of even a rare fault may be very serious unless the transformer is quickly disconnected from the system. This necessitates providing ....etc

MAGNETORHEOLOGICAL FLUID DAMPER
1.INTRODUCTION
Vibration isolators or dampers are commonly used to mitigate vibrations in structures or machines. The isolators are typically passive and they are designed to reduce the vibration of the most undesired frequency. However, in many applications, the excitation frequency varies across a large range. In a semi-active device, the stiffness or damping can be adjusted during operation. Changing the stiffness of the support device can be exploited by moving the eigenfrequency o ....etc

ABSTRACT:
The finite element program CRItical State Program (CRISP) has been used to model the New Austrian Tunneling Method (NATM) in London Clay. The non-linear behavior of the London Clay was modeled by a Strain Dependent Modified Cam Clay (SDMCC) model and the tunnel lining was modeled by constant and time-dependent classic models. The construction process was modeled in two and three dimensions by removing soil elements in sequence. The tunnel lining was either assumed wished-in-place or introduced after the excavation of each pa ....etc

Abstract”
In this paper, a real-time system to create a talking head from a video
sequence without any user intervention is presented. In the proposed
system, a probabilistic approach, to decide whether or not extracted
facial features are appropriate for creating a three-dimensional (3-D)
face model, is presented. Automatically extracted two-dimensional
facial features from a video sequence are fed into the proposed
probabilistic framework before a corresponding 3-D face model is built
to avoid g ....etc

ABSTRACT
The overall goal of the work presented in this thesis is to extend the physical understanding of the external aerodynamics associated with the rotating case of Hovering Rotor using Computational Fluid Dynamics (CFD) technique.
Rotating blades encounter tip vortices coming from preceding blades, which results in Blade Vortex Interaction(BVI) responsible for producing dynamic effects. Understanding the complex flow field due to this dynamic effects produced by wakes is therefore very important for the prediction of effects such as blad ....etc

INTRODUCTION
The aim of this project was to analyze and upgrade the existing generator protection system in BPCL-Kochi Refinery, Kochi. Power generation occupies the prime place in power system. Industrial and commercial power system may include generator as a local source of energy. These generators supply all or part of the total energy required or they ....etc

Over the last decade, particle tracking microrheology has matured as a new tool for complex fluids research. The main advantages of microrheology over traditional macroscopic rheometry are: the required sample size is extremely small (~ 1 mL); local viscoelastic properties in a sample can be probed with high spatial resolution (~1-10 mm); and the sample is not disturbed by moving rheometer parts. I will present two examples of recent work in my group that highlight how these characteristics can be exploited to acquire unique information about t ....etc

Abstract

A response surface model of the luminous flame emissivity of sodium pool fire has been proposed for use in safety analysis computer codes of a liquid metal fast reactor. The liquid sodium burns in air resulting in not only heat generation but also release of sodium oxide aerosols of sub-micron diameters. Aerosols levitating in air are radiative and they influence the allocation of combustion heat from the flame to atmospheric gas or sodium pool. The emissivity of the flame needs to be quantified, as it is one of user-specified param ....etc

Numerical Simulation for Aerodynamic Characteristics of Low Altitude and Subsonic Flight Vehicle
Abstract—In order to analyze the drag characteristics of the vehicle having different war head and empennage, the computational fluid dynamics numerical simulation was used. The method was based on fully hexahedral mesh and three-dimensional Navier-Stokes equations and Spalart-Allmaras turbulence model. Through numerical simulation the flow field structures and computational aerodynamic characteristics were obtained. T ....etc
