Abstract
A bladed expander for recovery of thermal energy from a working fluid, comprising a stator provided with an inlet port and an outlet port for the working fluid, a rotor housed within the stator, and a plurality of blades set between the rotor and the stator so as to delimit between them a plurality of compartments with variable volume that increases between the inlet port and the outlet port. The stator and the rotor are subjected to a heat exchange with a hot fluid so as to carry out a transformation of expansion during which the working fluid receives thermal energy from outside.
