Item Energy Harvesting from Vortex Induced Vibrations Using Vented Cylinders Mounted on Light Rail Locomotive(IEEE Computer Society help@computer.org, 2016) Kumar, K.R.; Morab, S.; Shekar, S.; Mahalingam, A.Majority of the population is dependent on the fossil fuels which are the conventional sources of the energy. Since fossil fuels are non-renewable they are bound to deplete in the near future. Leading edge research on the renewable sources of energy like wind energy, solar energy etc. Is a growing concern which has to replace the conventional energy sources to prevent environmental pollution and global warming. Wind energy is one among the renewable energy which is used for large scale power production using turbines, wind mills and power houses. Harvesting energy from vibrations caused because of alternative vortex shedding due to fluidic flow over a bluff body is under progressive research. The purpose of this study is to harvest wind energy from cross flow vibrations using vented cylinders mounted on the chassis of the train. In this study usage of vented cylinders over a normal baseline cylinder is of major concern to enhance vortex shedding and to extract maximum amount of energy considering a typical single carriage of a train. Using Computational fluid dynamics, Strouhal number is calculated which is validated and further designing a system for harvesting energy from vibrations. © 2016 IEEE.Item Simulation and analysis of energy harvesting from grey water and rain water in high rises(Institute of Electrical and Electronics Engineers Inc., 2016) Kumar, K.R.; Kulgod, S.P.; Anish, A.Leading edge research on the renewable sources of energy is on a rise in order to meet the increasing energy demand. The objective of this project is to harvest potential energy inherent in tall buildings using micro-pelton turbine at the ground from grey water and rain water. Purified water is collected in separate tanks and a control system is designed for optimum power output from the micro-turbine which is analyzed computationally. With the escalating number of high rises and increasing awareness about renewable sources of energy, this source of energy can become a viable alternative. © 2016 IEEE.Item Simulation and analysis of energy harvesting from Grey water and rain water in high rises(Institute of Electrical and Electronics Engineers Inc., 2016) Kumar, K.R.; Kulgod, S.P.Majority of the population is dependent on the conventional energy sources for their day today needs. Leading edge research on the renewable sources of energy is on a rise in order to meet the increasing energy demand without straining the environment. The objective of this project is to harvest potential energy inherent in tall buildings because of the high altitudes using micro-pelton turbine at the ground from grey water and rain water. Purified Grey water is collected in a tank placed at the centre of the building and rain water collection tank is placed at the top of the building. A control system is designed for optimum power output from the turbine and to monitor the levels of water. Separation and storage of used rainwater in a tank is also controlled. The pelton turbine is designed and further analyzed in ANSYS - Fluent, computationally for the power output. When number of high rises is escalating and awareness about rainwater harvesting and renewable sources of energy is indispensable, this source of energy will turn out to be viable option. © 2016 IEEE.
