· The kinetic energy of combustion gas is converted to mechanical power by the its impulse or reaction with a series of blades arranged around the circumference of a wheel or cylinder
· Stationary blades / guide blades act as nozzles and they convert fluid pressure into kinetic energy. The following rotating blades convert kinetic energy into useful work.
· Axial turbines have low pressure drop per stage and higher mass flow rate compared to radial turbines.
· The flow stream lines through the blading’s are nearly parallel to the shaft axis
· The flow stream lines through the blading’s are nearly parallel to the shaft axis.
· Flow enters axially and discharges almost axially.
· The blade passages converge from inlet to exit, and hence the flow accelerates.
· Blade profile is thicker at the inlet and thinner at the exit.
· Due to density variation from inlet to exit, the turbine end walls have flare with flow area increasing from inlet to exit.
