WebIn the turbine section of the gas turbine, the energy of the hot gases is converted into work. This conversion actually takes place in two steps. In the nozzle section of the turbine, the hot gases are expanded and a portion of the thermal energy is converted into kinetic energy. In the subsequent bucket section of the turbine, WebSep 18, 2024 · Enthalpy variation (∆En) consists of two components ∆En = ∆U + ∆ (pV). The first is the internal energy (∆U) of the fluid.
