Abstract: The results of computational and experimental sets, where low-frequency pulsations of total pressure in the jet obtained by various methods were studied and compared, are presented. The calculation was performed by the LES (IDDES) method using the EWT-TSAGI code. The experiment was performed using pressure gauges, sensors IKD-100 and Kulite. Visualization of the flow was performed. It is shown that the calculated and experimental data are in acceptable agreement with each other in all areas, except for the outer boundary of the jet, where the calculation grid has insufficient condensation.
Keywords: real scale wind tunnel, turbulence, large eddy numerical method, ring vortex, jet border, total pressure fluctuations.
