Abstract:
Vortex structures in subsonic and transonic jets of various initial profiles are numerically simulated. The mathematical models are based on conservative finite difference schemes that approximate conservation laws in the framework of the model of nonviscous perfect gas. The unsteady vortex structures are visualized. Pulsating characteristics of the flow are examined and compared with experimental data. Computations are performed using parallel algorithms implemented on a cluster architecture system. The influence of the parallelization scheme and the number of computing units on the performance of the algorithms is investigated. The approximation errors of realife computations are estimated using the differential approximation method.
