I'm doing a study on the convergence of acoustic data " surface acoustic power and volume acoustic power ..etc." ı found that k-epsilon turbulent method is more successful for converge surface acoustic power and k-omega is more successful for convergence volume acoustic power. ı am looking a best method for best converge all acoustic and flow performance data . Moment on blade surface fluctuating for last 500 iteration is %4 and outlet surface dynamic pressure fluctuating is %7 for the best method ı could find. for more ı am looking setup configurating at Fluent , especially pseudo time or courant number and k-epsilon or k-omega and control value.
