References. Tangential Flow c. Condition of fluid i. Many low speed transport aircraft and small commuter aircraft use turboprop propulsion. Two main categories of turbomachine are identified: first, those that absorb power to increase the fluid pressure or head (ducted and unducted fans, compressors, and pumps); second, those that produce power by expanding fluid to a lower pressure or head (wind, hydraulic, steam, and gas turbines). A Turbomachine is a device in which energy transfer occurs between a flowing fluid and the rotating element due to dynamic action resulting in change in pressure and momentum of fluid. Turbines used in thermal powerplants :-Also called as steam turbines, they are used in nuclear & thermal powerplants where water is heated to form steam & then flowed through turbines to produce electricity.
