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

Acoustic resonances in microfluidic chips: full-image micro-PIV experiments and numerical simulations [PDF]
, 2006 We show that full-image micro-PIV analysis in combination with images of transient particle motion is a powerful tool for experimental studies of acoustic radiation forces and acoustic streaming in microfluidic chambers under piezo-actuation in the MHz ...

Effect of Micro-Vortex Generator in Hypersonic Inlet
International Journal of Applied Research in Mechanical Engineering, 2011 In the present study computational tests were carried out to get an understanding of the flow field in a pure mixedcompression hypersonic inlet at a free stream Mach number of 7 and an altitude of 35km. Structured meshes have been used for depicting the motion of fluid inside the inlet. First, a grid has been selected after conducting a grid study. Two

Far-field measurements of vortex beams interacting with nanoholes [PDF]
, 2015 We measure the far-field intensity of vortex beams going through nanoholes. The process is analyzed in terms of helicity and total angular momentum. It is seen that the total angular momentum is preserved in the process, and helicity is not.
