Fluid is saturated with small and neutrally buoyant particles 18 Particle Image Velocimetry Principle of PIV operation ?Particles in flow scatter laser(s) light ?Two images, per camera, are taken within a small time of one another Δt. ?Both images are divided into identical smaller sections,...
The technique is therefore referred to as tomographic particle image velocimetry (tomographic-PIV). The reconstruction is performed with the MART algorithm, yielding a 3D array of light intensity discretized over voxels. The reconstructed tomogram pair is then analyzed by means of 3D cross-correlation...
This research deals with advanced developments in 3D particle image velocimetry based on the tomographic PIV technique (Tomo-PIV). The latter is a relatively recent measurement technique introduced by Elsinga et al. in 2005, which is bas... M Novara - 《Ipskamp Brukkers》 被引量: 9发表: 20...
Particle Image Velocimetry (PIV)Computer Fluid Dynamics (CFD)In recent years, minimum quantity lubrication (MQL) machining is regarded as a promising method for reducing machining cost and cutting fluid, while improving cutting performance. However the effectiveness and the working principle of MQL are...
Shi et al. designed a new Particle Image Velocimetry (PIV) experimental device and developed a gray-scale-based particle recognition algorithm for measuring the solid-phase distribution in centrifugal pumps. The device avoids stirring to reduce the influence of bubbles on PIV measurement [14,15]. ...
