Broadband Noise Reduction of a Two-Stage Fan with Wavy Trailing-Edge Blades
AerospaceIn this paper, a numerical investigation is performed to study the broadband noise of a fan stage with wavy trailing-edge blades. A study of the wavelength and ratio of amplitude to wavelength (H/L) is conducted to better understand the noise reduction ...

A Study of the Dependence of the Mach Stem Height on the Trailing Edge Height
Fluids, 2021 The Mach stem height is an important parameter in the Mach reflection of steady supersonic flow. Various experimental, numerical, and theoretical works have been conducted to study this parameter in the past. However, much of the established work focuses

Computation of Trailing Edge Noise with a Discontinuous Galerkin Method [PDF]
, 2010 Trailing edge noise of a semi-infinite, thin, flat plate situated in low Mach number flow is computed in two spatial dimensions. The Acoustic Perturbation Equations (APE), which are employed as governing equations, are discretized via a Discontinuous ...

Solitonic asymptotics for the Korteweg-de Vries equation in the small dispersion limit
, 2009 We study the small dispersion limit for the Korteweg-de Vries (KdV) equation $u_t+6uu_x+\epsilon^{2}u_{xxx}=0$ in a critical scaling regime where $x$ approaches the trailing edge of the region where the KdV solution shows oscillatory behavior.

Eigenvalues in trailing edge flows [PDF]
Journal of the Australian Mathematical Society, 1975 Abstract A wake similarity solution for symmetric uniform shear flows merging at the trailing edge of a flat plate has associated with it an eigenfunction problem which was overlooked by Hakkinen and O'Neil (1967). An asymptotic formula for large eigenvalues is obtained and compared with another such formula related to both the Goldstein (1930) inner ...

Aerodynamic behavior of an airfoil with morphing trailing edge for wind turbine applications [PDF]
, 2014 The length of wind turbine rotor blades has been increased during the last decades. Higher stresses arise especially at the blade root because of the longer lever arm.
