Alternative energy is a form of energy that can provide energy without the planet warming effects of fossil fuels like sunlight, geothermal heat, wind, hydro-power or Nuclear. From sunlight, we get energy in the form of solar energy, from the wind we get wind power energy, from the force of the river flow we get hydro energy. There is also geothermal energy available in nature. Those energies are called as the source of those energies will not get finished anyway.
In Alternative Energy, students need theoretical and practical knowledge to understand the entire concept of alternative energy with ease.
The course aims to provide an overview of the forms, purpose, principles, types of Non-Conventional Energy Resources, and their end-use technologies as applied to Engineering practice. It covers Renewable Energy Resources, Nuclear Energy, Energy storage systems, and Environmental impact.
The course aims to provide fundamental concepts of turbo-machines as applied to Engineering practice. It covers application to hydraulic machines, specific speed and machine selection, machine-system operation, application to axial flow compressors and turbines, radial turbines and compressors.
