1.1 Reminder of equations
We recall the equations of the supposed stationary flow, in their simplest form, i.e. one-dimensional, to specify the notations and assumptions.
a) Conservation of mass flow Q
m
of a fluid of density ρ passing through a surface S normal to the flow :
The flow velocity V can be expressed as a function of the Mach number M, and the flow rate then takes the form :
