Variation in aerodynamic coefficients with altitude

open access: yesResults in Physics, 2017
Precise aerodynamics performance prediction plays key role for a flying vehicle to get its mission completed within desired accuracy. Aerodynamic coefficients for same Mach number can be different at different altitude due to difference in Reynolds ...

Etude numérique et expérimentale de l'écoulement autour d'un rotor éolien [PDF]

open access: yes, 2013
An improved model of an actuator surface is proposed, representing the flow around a wind turbine. This model was developed in conjunction with a Navier-Stokes solver using a blade element method for the calculation of power and wake development.

Sand transverse dune aerodynamics: 3D Coherent Flow Structures from a computational study [PDF]

open access: yes, 2015
The engineering interest about dune fields is dictated by the their interaction with a number of human infrastructures in arid environments. Sand dunes dynamics is dictated by wind and its ability to induce sand erosion, transport and deposition.

Biofluiddynamic scaling of flapping, spinning and translating fins and wings [PDF]

open access: yes, 2009
Organisms that swim or fly with fins or wings physically interact with the surrounding water and air. The interactions are governed by the morphology and kinematics of the locomotory system that form boundary conditions to the Navier–Stokes (NS ...

Could the Coand\u{a} effect be called the Young effect? The understanding of fluid dynamics of a legendary polymath

open access: yes, 2011
A paper of Thomas Young (1773-1829) on the behavior of streams of air makes a good starting point for discussing the not always fair, sometimes serendipitous, association of a physical phenomenon with its discoverer.

A computational assessment of the aerodynamic performance of a tilted Darrieus wind turbine [PDF]

open access: yes, 2015
The aerodynamic performance of a Darrieus wind turbine operating with the rotation axis tilted with respect to the free-stream wind speed is investigated in this paper. An Unsteady Reynolds Averaged Navier Stokes (URANS) Computational Fluid Dynamics (CFD)

Computational simulations of near-continuum gas flow using Navier-Stokes-Fourier equations with slip and jump conditions based on the modal discontinuous Galerkin method

open access: yesAdvances in Aerodynamics, 2020
Blunt-body configurations are the most common geometries adopted for non-lifting re-entry vehicles. Hypersonic re-entry vehicles experience different flow regimes during flight due to drastic changes in atmospheric density. The conventional Navier-Stokes-
