A device 1, 100, 101, 102, 103 for converting heat into mechanical energy comprises a channel flow boiler 8, 22 adapted to heat a working fluid 13 to generate a liquid-gas mixture 33; an expansion device 9, 23 adapted to expand the liquid-gas mixture; and a movable element 10 arranged such that the expanding liquid-gas mixture to convert its internal and/or kinetic energy into mechanical work. Further, a method for converting heat into mechanical energy is disclosed, wherein the method comprises: heating S1 a working fluid for generating a liquid-gas mixture; expanding S2 the liquid-gas mixture; providing heat S3 to the liquid-gas mixture, and converting S4 the internal and/or kinetic energy of the liquid-gas mixture into mechanical energy associated with the movable element, wherein the method is operated as a thermodynamic cycle such that the expansion of the liquid-gas mixture is partially approximately isothermal. |
