Abstract

Numerical simulation of unsteady airwakes of a simplified frigate model (SFS) was performed with structured grids, third order MUSCL spatial discretization scheme, second order implicit temporal discretization scheme, and LES turbulence model. The results show that velocity fluctuation of SFS airwakes is violent. The dominant frequencies of unsteady flow are less than 1Hz. Time-averaged unsteady results by unsteady method do not agree well with the steady results by steady method, with a maximum discrepancy, 10%. The numerical model was verified by previous experimental data, and the two showed a good agreement.
