Numerical Simulations of a Subsonic/Supersonic Coaxial Jet for an Efficient Design of Experimental Setup
发布日期2014
The flow field of a coaxial jet with the internal (primary) flow being subsonic and the external (secondary) flow being supersonic has been investigated with COMSOL Multiphysics® software. We used the results to correct defects in the nozzle geometry and we evaluated the effect of heat transfer on the shock-cells system. Finally, we verified the stresses in the material to avoid permanent deformations in the nozzle. The simulations will be used to design efficiently the experimental setup for aeroacoustic and optical measurements.
