in two phases

in three phases

in a single phase

in the form of air and water mixture

increases thermal efficiency

allows high compression ratio

decreases heat loss is exhaust

allows operation at very high altitudes

3.5 : 1

5:1

8:1

12:1

high thermal efficiency

reduction in compressor work

decrease of heat loss in exhaust

maximum work output

increase temperature

reduce turbine size

increase power output

increase speed
