Most of the gas turbines employ the axial flow turbines.
The article is concerned with axial flow turbines.
The radial turbine can handle low mass flows more efficiently than the axial flow machines.
Elementary Theory of Axial Flow Turbine:
The velocity triangles for one axial flow turbine stage and the nomenclature employed are shown. The gas enters the row of nozzle blades with a static pressure and temperature P1, T1, and a velocity C1, is expanded to P2, T2, with an increased velocity C2 at an angle Alpha2
