ACOUSTIC EXCITATION OF NONCIRCULAR TURBULENT JETS
E. V. Vlasov, A. S. Ginevskii, R. K. Karavosov, and T. M. Makarenko UDC 532.525.2:534.2 Results of experimental investigation of turbulent mixing in jets flowing out of nozzles with different cross sections in the case of low- and high-frequency acoustic excitation of the jets are presented. The influence of the shape of the cross section of a nozzle on the acoustic-excitation sensitivity of a jet flowing out of it is analyzed.
