WebOct 11, 2024 · For flow around elongated bluff bodies, flow separations would occur over both leading and trailing edges. Interactions between these two separations can be established through acoustic perturbation. In this paper, the flow and the acoustic fields of a D-shaped bluff body (length-to-height ratio L/H = 3.64) are investigated at height-based ... Weba fuel jet surrounded by a bluff-body and co-flowing air. The diameter of jet, DJ, is 3.6mm and the diameter of bluff-body, DB, is 50mm. The jet fuel is a mixture of methane, CH4, and hydrogen, H2, 1:1 by volume, with the bulk velocity, UJ = 118m/s. The co-flow velocity is UC = 40m/s. There is a recirculation zone immediately downstream
