  Can I use the LES model to calculate the Pressure at Inlet and Outlet, for compressible flow? n

  Yes sure and regarding the graph it is showing a divergent behavior. Regarding usage of LES which is very expensive: Why? What is your task?n

  I have to calculate the mass flow rate in the inlet and outlet of the nebulizer head. I have the Boundary conditions for inlet 4,5,6,7,8,9,10 bar and Outlet as approximately 1bar absolute. n

  Yes, you can solve that, but you will need to make sure the mesh is good and the initial conditions are fairly close to reality. Setting the mass flow rate and calculating the pressure drop is easier, and will give you the same graph overall. n
