In this article we present a quick and accurate method to calculate the aerodynamic conference -
that is very important for light aircrafts – we developed program depend on “VORTEX LATTIC
METHODS” we calculate the distribution of local lift forces
according to wing profile. in the Earle
stage of designing we concrete on lifting properties of aircraft because it effects at fighting safety
where these aircrafts used mechanical direct control system. for this, accurate estimation of lift and
moment conferences for wings and stabilizers have very big importance.
Developing The numerical tools which depend on simple and accurate module produced by
“VORTEX METHOD” is very effective tools in this stages for all kind of wings.
In this study, SST satellite images analysis (from
September 2015 to November 2016) is focalised on the
monitoring of the mesoscale eddies in the eastern Levantine subbasin
(at the Syrian coasts as well as the neighboring coasts).
SST satellite images analysis has showed many
characteristics for a lot of mesoscale eddies in the Eastern basin
of the Mediterranean Sea. In this study, the SST analysis is
focalised on the mesoscale eddies` formation at the Syrian coasts.
We are also interested by their characteristics for their influences
on the marine environment .
The aim of this paper is to investigate the overlap between lower atmospheric boundary layer and real wind turbine wake which installed not far from ground surface, Here we adopted rotating actuator-disk model (RADM) as a complex model of 3D actuator
-disk model, virtual blade modeling (VBM) and tip loss correction, in order to get more reliability and satisfied result.
Wind turbines have grown significantly in size over the last years and, it generally placed in an atmospheric boundary layer, then the assumption of uniform wind velocity cannot be valid.
The lower part of atmospheric boundary layer has a high level of turbulence intensity and great velocity gradients, then when wind turbine placed in these conditions, a high rate of fluctuation will occur subsequently power losses in wind farms, and change wake turbulence character which affects the flow-induced dynamic loads on downwind turbines.
