Present paper describes the correlation between occurrence of cavitation inside injector nozzle and progress of atomization in discharged liquid jet flow. A transparent two-dimensional shape nozzle was designed and it was used for flow visualization. The visualized images both of cavitation and atomization were obtained simultaneously. The cavitation was evaluated by applying image analysis. The q...... hiện toàn bộ
On the aerodynamic flow around a cyclist model at the hoods positionJournal of Visualization - Tập 23 - Trang 35-47 - 2019

Aerodynamic flow around an 1/5 scale cyclist model was studied experimentally and numerically. First, measurements of drag force were performed for the model in a low-speed wind tunnel at Reynolds numbers from $$5.5 \times 10^{4}$$ to $$1.8 \times 10^{5}$$. Meanwhile, numerical computation using a large eddy simulation method was performed at three Reynolds numbers of $$1.1 \times 10^{4}$$, $$6.5 ...... hiện toàn bộ
Three-dimensional vortex structure using phase-averaged stereoscopic PIV for an oscillating airfoilJournal of Visualization - Tập 18 - Trang 553-561 - 2015
T. Haniu, H. Hasegawa
A quasi-steady-state approach to the prediction of fluid forces acting on an insect wing leads to errors that suggest that flight is impossible. However, because biological flight does occur, the effect of unsteady fluid forces must be important to flight. The propulsive forces of these animals are related to unsteady fluid forces accompanied with the movement of vortices. Therefore, unsteady flui...... hiện toàn bộ
Hierarchical facial data modeling for visual expression synthesisJournal of Visualization - Tập 6 - Trang 313-320 - 2003
Y. Zhang, E. C. Prakash, E. Sung
This paper presents a new method for modeling of a personalized 3D face model that has a hierarchical structure of the skin, muscle, and skull for realistic expression synthesis. We start from an accurate facial mesh reconstructed from the individual face measurements. The deformable skin model has a multi-layer structure to approximate different types of soft tissue and takes into account the non...... hiện toàn bộ
A novel in situ compression method for CFD data based on generative adversarial networkJournal of Visualization - Tập 22 - Trang 95-108 - 2018

As one of the main technologies of in situ visualization, data compression plays a key role in solving I/O bottleneck and has been intensively studied. However, existing methods take too much compression time to meet the requirement of in situ processing on computational fluid dynamics (CFD) flow field data. To address this problem, we introduce deep learning into CFD data compression and propose...... hiện toàn bộ
