Jet Propulsion/Gas turbine energy exchange
In a gas turbine processes energy is converted from one form to another.
Kinetic energy to fluid temperature
Changing the velocity of the fluid by pressure changes simultaneously changes the temperature. Compression work raises the apparent temperature of the fluid. We can relate Mach number to the internal energy of the fluid:

Work addition to the fluid by blades
Combustion energy addition
Heat transfer to and from walls
