TITLE : COLD FLOW NUMERICAL SIMULATION OF A TWO-DIMENSIONAL
NOZZLELESS SOLID ROCKET MOTOR
BY : Aerospatiale - J F Chauvot
DATE : 1992
- PHOENICS has been used to simulate the flow in a nozzleless
solid rocket motor
- Two-Dimensional steady flow
- k-e turbulence model used.
- Both inviscid and turbulent computations were done.
- The results are compared with experimental pressure and velocity data.
- There is one-dimensional solution to this problem, which is also
compared with the experimental results.
The pictures are as follows:
Computational domain and close-up of the grid used for the turbulent computations.
Pressure distribution vs normalised axial distance.Both experimental and PHOENICS results are shown.
Axial velocity component vs normalised axial distance, on the symmetry axis.
Full details of the PHOENICS simulation and the experimental
results may be obtained in:

- The pressure is well predicted by all the models when the flow
is laminar (x/L < 0.6).
- In the turbulent region (x/L > 0.6) the turbulent PHOENICS
solution gives the most accurate results.
- When the measurements of velocity are compared, the turbulent
PHOENICS solution gives extremely good results at all points
along the chamber.
