Splet11. apr. 2024 · To effectively reduce the loss of strong shock wave at the trailing edge of the supersonic cascade under high backpressure, a shock wave control method based on self-sustaining synthetic jet was proposed. ... The blade surface was assumed to be adiabatic non-slip wall. The upper and lower boundary were set as translational periodic … Splet01. okt. 2024 · Although trailing-edge noise is broadband noise, it has a distinct peak frequency where noise becomes maximum. For example, the peak frequency that is estimated based on the energetic fluctuations in the boundary layer near the trailing-edge is expressed as f δ ∗ ∕ U ∞ = 0. 06 − 0. 08 [1] where f is a frequency, δ ∗ is a boundary layer …

SpletMomentum Thickness ( θ) Momentum thickness is defined in relation to the momentum flow rate within the boundary layer. This rate is less than the rate that would occur if no boundary layer existed, when the velocity in the vicinity of the surface, at the station considered, would be equal to the mainstream velocity Ue.
