1. The problem statement, all variables and given/known data A 2-D nozzle shown in picture 1 is to be analyzed. The nozzle is working with critical condition at the throat. I haven attached a Pdf and .jpg file for the figure ReD* :230000 D* :6mm T0 :300 K Diffusor half angle : 3° Diffusor lenght :7D Medium :Air Κ :1,4 R :287 J/kgK μ0 :18,6.10-6 Pas ρ0 :1,2 kg/m³ 2. Relevant equations By using the following equations m/A=P0√κ/√RT0(1+κ−1/2M2)κ+12(κ−1) (1) ReDx= 4m/∏Dx ν (2) 3. The attempt at a solution I have no idea how to solve analytically please guide me 1) Solve analyticaly the 1st, 2nd and 3rd critical poit. Choose a pressure ratio for a shock in the diffusor part. Solve all the values (p, T) for the exit. Put the values in to starCCM+ and compare your analytical results with the results from starCCM+. 2) Solve the location of the shock and compare the position from your result with starCCM+. 3) Plot all the pressure distributions from starCCM+ along the axis in one graph. (p/p0 vs position). 4) Compare the time averaged massflowrate with the theoretical massflow. Do you have some differences.
