Summary: | Modification of the serial Fortran code for solving unsteady 2-D Euler
equations for the mixture of compressible gas and polydisperse particles was
carried out using OpenMP technology. Modified code was verified and parallel
speed-up was measured. Analysis showed that the data on parallel efficiency
is in a good agreement with the Amdahls law, which gives the estimate for
serial code fraction about 30%. Parallel code was used for the numerical
simulation of two test-cases, namely shock wave propagation in 2-D channel
with obstacles filled with reactive Al-O2 gas particle mixture and
heterogeneous detonation propagation in polydisperse suspensions. For the
first test-case the data on particles distribution in the flow was obtained,
the existense of particle free zones inside the vortices was demonstrated
and the attenuation of a shock wave was studied. In the second test,
numerical simulation of detonation shock wave propagation in plain 2-D
channel for the three polydisperse mixtures was carried out and data on
detonation regimes was also obtained.
