...Mattias E. G. Eck; Philipp zur Nedden; Jakob G. R. von Saldern; Christoph Peisdersky; Alessandro Orchini; Christian Oliver Paschereit Swirling flows are commonly used for flame stabilization in gas turbine combustors, which are hence equipped with suitable swirler units. In these units the air...

..., the literature on external forcing of swirl flows is much more limited. An experimental forced response analysis of swirling flames was done by Manoharan et al. in Ref. [ 6 ]. A local and weakly, global forced response analysis with external acoustic forcing based on Wentzel–Kramers–Brillouin–Jeffreys assumption...

... such as swirl accurately. In this study, the GEKO model is used for simulating RANS predictions of turbulence in a swirling flow scenario, whereas high-fidelity LES predictions serve as target data enabling field inversion via gradient-based optimization using the Adjoint solver in ansys fluent . Machine...

... results give new insight into the flow dynamics of a swirling flow burner under strong forcing. As the PIV phase locked measurement showed that the structure is traveling downstream, only the sense of rotation (i.e., clockwise or counterclockwise rotation) determined at one axial position...
