摘要: A prediction method based on the generalized acoustic analogy is presented, and used to evaluate aerodynamic noise radiated from high speed hot jets. The set of Euler equations are split into their respective non-radiating residual components. Under certain conditions, rearranged form a wave equation. This equation consists third-order operator, plus number nonlinear terms that identified with equivalent sources sound statistical characteristics modeled. specialized RANS solver provides base flow as well turbulence quantities temperature fluctuations determine source strength. main objective here relative contribution various elements far-field spectra show significance in
