Noun. 1. reaction turbine-a turbine with blades arranged to develop torque from gradual decrease of steam pressure from inlet to exhaust. turbine-rotary engine in which the kinetic energy of a moving fluid is converted into mechanical energy by causing a bladed rotor to rotate.. (Mechanical Engineering) a turbine in which the working fluid is accelerated by expansion in both the static nozzles and the rotor blades. Torque is produced by the momentum changes in the rotor and by reaction from fluid accelerating out of the rotor. Compare impulse turbine.
