Gas Turbine Engineering

Abstract

Gas turbines are used in various applications such as power generation, mechanical drive, jet engines and ship propulsion because they offer high efficiency, low emissions and flexibility. This course dives into the key engineering aspects associated with gas turbine design and operation.

Objective

Differentiate major gas turbine types, applications, and performance drivers. Perform engine cycle analysis and assess system integration and optimization strategies. Explore design and operation principles of compressors, combustors, and turbines, including emissions and cooling considerations. Evaluate materials, structural integrity, and failure mechanisms under high-temperature loading. Apply principles of control, monitoring, and rotor dynamics for reliable turbine operation.
