In this paper the turbulence effects are studied for three rotors mounted on same instrumented hub. Two scaled models of industrial turbines and one open-geometry turbine considered. The characteristics obtained from 2D Laser Doppler Velocimeter measurements behaviour is analysed thrust torque measurements. Three intensities a large range tip speed ratios flow velocities results anonymised in o...

PURPOSE There is a long-standing interest in the study of retinal blood flow in humans. In the recent years techniques have been established to measure retinal perfusion based on optical coherence tomography (OCT). In the present study we used a technique called dual-beam bidirectional Doppler Fourier-domain optical coherence tomography (FD-OCT) to characterize the effects of 100% oxygen breath...

Abstract The development of a low-cost Video Velocimeter (VIV) to estimate underwater bulk flow velocity is described. instrument utilizes simplified particle image correlation technique reconstruct an average vector from video recordings ambient particles. VIV uses single camera with set mirrors that splits the view into two stereoscopic views, allowing estimation vector. was validated in cont...

The Hugoniot elastic limit and spall strength were measured for a heat-resistant metal-matrix composite Inconel 625–5%NiTi–TiB2 alloy additive manufactured (AM) by direct laser deposition. characteristics of the obtained from analysis complete wave profiles recorded with VISAR Doppler velocimeter during shock-wave loading samples. samples loaded using PP50 pneumatic gun or ad hoc explosive devi...
