Webb12 apr. 2024 · The jet deforms by d f /d 0 ∼ 1.9 (d 0: jet diameter and d f: local width of jet at the point of breakup). The interaction of the air jet initiates instabilities in the water jet. This is evident by the shear-stripping of the jet into ligament-type structures (average length and width of the ligaments are l lig ∼ 0.3 mm, d lig ∼ 0.03 mm) at the periphery [ … Webb11 apr. 2024 · Three-dimensional turbulent flow and convective heat transfer in pulsating impinging jet flow on a surface mounted by elliptical pin-fin were numerically and experimentally investigated. The spacing between jet and surface ( H/D ) in the range of 2 to 6, the frequency between 10 and 100 Hz, and different aspect ratios ( AR< 4) have …

Webbfor the turbulent regime. Because of that, jets impinging on solid surfaces have been used to assess the predicting capabilities of computational codes and turbulence models (Cooper et al., 1993). A review of the literature shows a significant number of studies of the classical non-swirling jet impingement configuration.
