IIJ03-04-01: SIRMOUR’s HYDROELECTRIC POWER PLANT’S RELIABILITY FACTORS AND THEIR RELIABILITY ASSESMENT
AUTHORS: Harshad Dhote, Mr. Pankaj Mishra
ABSTRACT: Water is one of the best renewable energy sources available, as we are almost totally dependent on the availability of depleting fossil fuels. Being more reliable and cost effective hydro energy is attracting more investors and entrepreneurs for investing and establishing hydro power plant. Since maintenance and operation of a power plant isvery complicated and the process, calculating and analyzing its compatibility and reliability is very important. This paper introduces Markov reliability model for THPS-I, MPPGCL Sirmour, India by studying the operational data and analysis of all parts of generating unit of the power plant for period of 2010-2015. The availability and reliability of individual unit of power plant is evaluated by taking into account different indices, namely failure rate (λ), repair rate (µ), MTTR, MTTF, MTBF through data collection and tabulating all types of failures for separate analysis. By these evaluation and analysis we can improve reliability of all the components of each unit of power plant. The error of a single sub-unit can affect the annual performance and efficiency of power generation. Thus this modeling technique will help to decrease repair cost, identifying sensitive equipment’s to be replaced. And probably errors can be removed that make more power available at low cost as per given input, and allow a fair step towards energy independence of local community. The sub-unit that is commonly failed during operation is like- penstock, butter fly valve, spiral case, turbine, generator, excitation system, speed governor etc. Reliability plays a key role in the cost-effectiveness of systems

IIJ03-04-02 : Review on iot-aware, smart system for automatic monitoring and tracking of patients, and biomedical devices within hospitals and nursing institutes
AUTHORS: Rahnuma Gaffar Khan, Mr. Gurpreet Singh
ABSTRACT: Technology plays the vital role in healthcare not only for sensory devices but also in communication, recording and display device. It is very important to monitor various medical parameter and post operational days. Hence latest trend in Healthcare communication method using IOT is adapted. The IoT has a variety of application domains, including health care system. The IoT revolution is redesigning modern health care with promising technological, economic, and social prospects Among others, mainly radio frequency identification(RFID), wireless sensor network (WSN), and smart mobile technologies are leading this evolutionary trend. In the wake of this tendency, this paper proposes a survey on novel, IoT-aware, smart system for automatic monitoring and tracking of patients, personnel, and biomedical devices within hospitals and nursing institutes. Staying true to the IoT vision, a smart health care and management system (SHS), which relies on different, yet complementary, technologies, specifically RFID, WSN, and smart mobile, Internet of things serves as a catalyst for the healthcare and plays important role in wide range of healthcare applications.

IIJ03-04-03: CFD SIMULATION OF BOILING PHENOMENON OF WATER FOR OPTIMIZATION BY USING FLUENT
AUTHORS: Prashant kumar Mishra, Mr. Rahul Kumar Singh
ABSTRACT: The nucleate boiling is the current promising way for heat transfer and for calculating the critical heat flux. The understanding of the thermal and hydrodynamic features of the flow plays a fundamental role in this study. The current experimental techniques are still inadequate to capture the small scales involved in the flow, while the recent advances in the multiphase CFD techniques provide innovative tools to investigate the two-phase flow. However, the scientific literature concerning with numerical modeling of flow boiling patterns is still poor, such that several aspects of the flow are not clarified yet. In order to save lots of procedure time, the flow is sculptured with an axis y metrical formulation in fluent Ansys 14.5.The purpose of this study is to demonstrate the modeling of forced convection sub-cooled nucleate boiling using the in-built boiling model available under Eulerian multiphase model. The exact position of bubbles volume fraction is obtained by considering all these parameters. This will make easier the estimation of volume fraction at x=0.1,0.2,0.3……n points. This method reduces the calculating time for critical flux which makes very industrial work easier.
