The invention relates to a method for increasing the efficiency of a turbomachine, wherein a fluid guided through the turbomachine transfers kinetic energy to the turbomachine. The object of the invention is to increase the efficiency of a turbomachine. This object is achieved in that the fluid or at least one fluid component of the fluid is compressible, and that the flow velocity of the fluid reduced in the turbomachine (1) during the transfer of kinetic energy is increased directly downstream of the turbomachine (1) by a force F.sub.B generated by means of a force field and acting in the direction of flow, by converting potential energy of the fluid into kinetic energy of the fluid to such an extent that the pressure of the fluid, which is reduced in the turbomachine (1), is thereby increased again to at least 0.1 times the pressure of the fluid upstream of the turbomachine (1).
