Description

This professional course on Gas Turbine Engineering contains a detailed study on gas turbine that is used for power generation in various applications like aircrafts, automobiles, and marine and also in various industrial applications.  
Gas turbines are a kind of internal combustion engine where the combustion takes place inside the engine chamber. This turbine is also called as combustion turbine that can convert chemical energy (gaseous or liquid fuels) into mechanical energy. This mechanical energy is used to drive a generator that generates electrical energy.
The course will deal about the fundamentals of gas turbines, classifications, thermodynamic analysis, gas turbine parts and their materials, lubrication system, fuel supply system, performance and mechanical standards followed, condition monitoring and optimization systems, Maintenance methodologies and improvement techniques. Detailed concepts on Gas turbine will be discussed. The present and future technologies with their advancements are further discussed.
A case study on Combined Cycle Power Plants Gas Turbine will practically discussed by the lecturer to learners which will provide a combination of practical as well as technical information on the subject.
Students (fresher or experienced, technical or non-technical professional) will gain hands on experience on application of engineering on their current industrial platform
