1. Losses and energy balance of a turbomachine

Turbomachinery losses can be classified in two different ways:

if we consider their physical nature, they are subdivided into :
- aerodynamic vane (or hydraulic) losses, the main cause of which is the viscosity of the fluid, and which are mainly manifested in any fixed or moving channel by a head loss term (§ 1.2.1 );
- disc friction losses (§
