Open Journal of Fluid Dynamics, 2017 We have developed an LES (Large-Eddy Simulation) code called RIAM-COMPACT (Research Institute for Applied Mechanics, Kyushu University, Computational Prediction of Airflow over Complex Terrain). The analysis do-main of this numerical model extends from several meters to several kilometers.

Numerical Study of the Effect of Freestream Turbulence on by-pass Transition in a Boundary Layer [PDF]
, 2014 We use direct numerical simulations in the presence of free-stream turbulence having different values of intensity, T u, and integral length scale, L, in order to determine which kind of structures are involved in the path to transition of a boundary ...

Coherent polarization shift keying modulated free space optical links over a Gamma-Gamma turbulence channel [PDF]
, 2011 Problem statement: The optical signal propagating through the Free Space Optical (FSO) channel suffers from irradiance and phase fluctuations caused by the atmospheric turbulence, which results in Bit Error Rate (BER) performance degradation ...
