FIG. 1. Flow configuration and geometry, detailed in [13].
FIG. 2. Power spectrum density of the lift (left, Fluent), and phase portrait (CL,CD) for several angles of attack α obtained by Fluent (middle) and CharlesX (right).
FIG. 3. Mean ( ¯ CL, 10 ¯ CD and ¯ CL/10 ¯ CD) and RMS (C rms
FIG. 4. Five instantaneous vorticity fields and contours for the three angles of attack obtained by CharlesX: α = 7 ◦ (linear), 8 ◦ (chaotic), and 9 ◦ (non linear)

In this paper, using techniques similar to those MacKenzie used to study SPEKE SPEKE in [17], we proved the security of a slight variant of Dragonfly Dragonfly, which gives

In 1997, several papers (Nijmeijer and Mareels, 1997)(Itoh et al., 1997)(Millerioux, 1997)(Grassi and Mascolo, 1997) have brought out a connection between the chaos

To see that a qualitative argument can be used: we know that the completely ordered case minimize the energy and we are interested in the states that have the closer possible

The benefits of HM are well-documented ( 6 ) and most of them are related to the immune component ( 2 , 3 ) The aim of the study was to assess LF, IgA, and LZ content of donor HM

In order to understand which process is responsible for the collapse of the 222 Rn and its short-lived daughters concentration in unsteady atmospheric boundary layers, we focus in

We successfully developed a general air-side feed stream con- tamination model, which has been validated with experimental data on fuel cell toluene contamination at four

Basé sur l’état de l’art des dispositifs de mesure de trajectoire dont le bilan a été dressé dans le chapitre 1.2.6, ce chapitre propose une approche innovante, se concentrant sur
