3.1Physical Problem Description
The probem geometry and flow conditions in this chapter are as describe
in the first point, except that the flow is no longer isothermal and the
incoming air is at a temperature of 350 K. The additionnal physical complexity
comes from the fact that a water spray is injected at the inlet to increase
the concentration of the water vapour in the air stream. The amount of
liquid injected is 6.09 10^6 kg/s. The phisical properties of the liquid
and the initial droplet diameter,
temperature and velocity are as follows :
Density (kg/m3)  Specific heat
J/(kg K) 
Latent heat of vaporisation (J/kg)  Pressure of saturation (Pa)  Surface tension coefficient (M/m)  Diameter (m)  Initial temperature (K)  Initial velocity (m/s) 
995  4179  24.25 E5  4858  0.072  4.0 E5  305  (10.,10.,0.) 
3.2Modelling strategy
The following modelling strategy model is adopted :
