- Which part of a turbulent jet generates noise and which propagates it? Noise generated by turbulent jets has been a controversial subject since Lighthill’s times. Until recently, many jet noise theories were based either on phenomenological approaches or rigorous mathematical formulations but with making several approximations in order to obtain a practically feasible noise prediction scheme. Here, we developed the first consistent framework, which rigorously incorporates the state-of-the art acoustic analogy formulation with an assumption free implementation for the use in unsteady CFD methods. The work led to a guest editorship of the Special Issue of Royal Society PhilTransA (2019).
