“…The PSD is usually used to understand the transport of coherent structures and the related energy dissipation process. In the LES modeling, the criterion for a grid of sufficient fineness is that it can resolve the inertial range to get meaningful results 32 . According to the Kolmogorov −5/3 theory, the characteristic slope (−5/3) of the inertial range can be used for the test.…”

In this study, effect of swirling addition on the liquid mixing behavior of multiorifice‐impinging transverse jet mixer has been investigated by planar laser‐induced fluorescence as well as large eddy simulation (LES). In the case of swirling addition into the jet flow, there exists an optimized swirling jet angle or optimized jet‐to‐cross velocity ratio for the fixed mixer configuration. A larger swirling jet angle will make the flow dominated by the swirling, resulting in a slower mixing process. Interaction of swirling crossflow with no‐swirling‐injected streams, or with swirling‐injected streams in the opposite direction is beneficial for the mixing. LES predictions show that many small vortices are produced homogenously due to intensified impingement in the case of opposite swirling directions, leading to a relative fast mixing process in few milliseconds. Whereas the mixing is restrained when the swirling directions of two flows are the same.
