Distribution of Acoustic Power Spectra for an Isolated Helicopter Fuselage
EPJ Web of Conferences, 2016 The broadband aerodynamic noise can be studied, assuming isotropic flow, turbulence and decay. Proudman’s approach allows practical calculations of noise based on CFD solutions of RANS or URANS equations at the stage of post processing and analysis of ...

Sobre la convexidad de la función de presión en el problema de la filtración no lineal
Revista de Matemática: Teoría y Aplicaciones, 2009 We prove the convexity of the pressure function v for the isotropic ideal gaz flow, based on the theorem about the zeros of the solution of the parabolic equation (1) Keywords: fluid mechanics, turbulence, parabolic ...

Unsteady and Inhomogeneous Turbulent Fluctuations around Isotropic Equilibrium
AtmosphereExtracting statistics for turbulent flows directly from the Navier–Stokes equations poses a formidable challenge, particularly when dealing with unsteady or inhomogeneous flows.

New Journal of Physics, 2018 In statistically stationary conditions, the turbulent energy spectrum in a high Reynolds number flow exhibits a k ^−5/3 (Kolmogorov) regime, with a faster decay at larger, dissipative wavenumbers.

Quarterly Journal of the Royal Meteorological Society, EarlyView.A theory for the interaction between a boundary layer and a low mountain is used to provide estimates of the turbulent orographic form drag, upward‐propagating mountain gravity‐wave drag, and trapped lee‐wave drag (case shown in the figure). After reviewing briefly how these processes are represented in weather and climate models, we propose a ...
