Particle image velocimetry (PIV), as a common technology for analyzing the global flow motion from images, plays significant role in experimental fluid mechanics. In this article, we investigate deep learning-based techniques such estimation problem. The aim of novel technique is to extract 2-D velocity fields images efficiently and accurately. First, introduce convolutional neural network (CNN) called LiteFlowNet, which proposed end-to-end optical estimation. Enhanced configurations...
Shangwan coal is a low-rank from inner Mongolia. particles show electronegativity in the slurry, because there are many oxygenated functional groups, such as carboxyl group, hydroxyl and carbonyl group on surface core of particles. Besides, these groups all hydrophilic, shows strong water-retaining capacity. Hence, coal–water slurries (CWSs) made contain little free water, their concentration low. In this paper, we used four different chemicals to coat investigate corresponding effects...
Tomographic particle image velocimetry (Tomo-PIV) has been successfully applied in measuring three-dimensional (3D) flow field recent years. Such technology highly relies on the reconstruction technique which provides spatial distribution by using images from multiple cameras at different viewing angles. As most popular method, multiplicative algebraic (MART) advantages high computational speed and accuracy for low seeding reconstruction. However, is not satisfactory case of dense...
Particle tracking velocimetry (PTV) is a powerful technique for global and nonintrusive flow field measurement, which shows great potential to improve the spatial resolution compared other visualization technologies (e.g., correlation-based particle image velocimetry). However, performing PTV under conditions with high speed density still challenge. In addition, more research sacrifices computational efficiency accuracy using complex iterative algorithms. To address these problems, we...
In this paper, a new sub-pixel intensive particle image identification method used for tracking velocimetry (PTV), is discussed. With aiming to improve the performance of accuracy and robustness, two-stage deep learning framework consisting two independent convolutional neural networks (CNN) proposed in method. The first network segment blobs from image, second one locate position segmented particles at level. A synthetic dataset containing images ground-truth positions generated training....
With the development of technology digital camera, performance image sensor is continuously improving, which makes it possible to measure leaf area index by photos in a simpler and cheaper way compared with other ways. This article proposed new LAI using images, formulation measuring deduced from both principle LAI2000 theory camera. Considering system error, modified formula also deduced. In this article, there are about 35 measurement locations include kinds different density canopy, where...
