Sentence examples for leading edge separation from inspiring English sources

Six different leading edge separation angles were created by altering the leading edge geometry.

The leading edge separation takes place in the following condition [15]: C N, n ' > C N, I Open image in new window.

The fine resolution of pressure taps allowed the extent of leading edge separation bubble, pressure recovery region, and effect of sail curvature to be observed quite clearly.

The results show a linear decrease in the shedding frequency of nearly 40% as the leading edge separation angle is increased from 0° 90°.

From the phase averaged data, the velocity outside of the recirculation region is observed to decrease markedly as the leading edge separation angle is increased, which is suggested to be responsible for the observed changes in the shedding frequency.

The contribution of the leading edge separation C N, n V Open image in new window is calculated using: C N, n V = C N, n − 1 V ⋅ exp − ΔS T v + C V, n − C V, n − 1 ⋅ exp − ΔS 2 T v if α n d C V dt ≥ 0 and 0 < τ V n < 2 T vl C N, n − 1 V ⋅ exp − ΔS T v Open image in new window (16) C V, n = C N, n C 1 − K N, n Open image in new window K N, n = 1 + f n ' ' 2 2 Open image in new window.

This paper demonstrates that, when optimised properly, the add-on type leading edge serration can be very effective in both the reduction of the interaction broadband noise, and the suppression of the boundary layer separation at high angle of attack.

The increased flow at the leading edge leads to a severe adverse pressure gradient, resulting in immediate leading-edge flow separation.

The perturbation at leading edge and the flow separation at strut back lead to vorticity augmentation and velocity decrease at the vicinity of strut bound.

In this numerically challenging flow, a thin recirculation zone with highly anisotropic turbulent structures is formed close to the leading edge after boundary layer separation.

At the leading edge, the flow experiences laminar separation-laminar reattachment state (1.5e3 < Re < 6e3), laminar separation-turbulence reattachment state (6e3 ≤ Re ≤ 8e4), and turbulence separation-turbulence reattachment flow state (Re > 8e4).
