cfd simulation and High Speed Photography of liquid flow in the outer cavity zone of a rotating packed bed reactor
Industrial & Engineering Chemistry Research, 2019Co-Authors: Yi Liu, Yong Luo, Guangwen Chu, Wei Liu, Baochang Sun, Jianfeng ChenAbstract:The outer cavity zone, having numerous moving liquids, is an important mass transfer zone in a rotating packed bed (RPB) reactor. However, investigation of the liquid flow in the outer cavity zone is scarce. In this work, liquid flow in the outer cavity zone of the RPB reactor with nickel foam packing was studied by computational fluid dynamics (CFD) simulation and then verified by High-Speed Photography technology. Large eddy simulation and volume of fluid model were adopted to predict the liquid flow pattern, average diameter, and velocity of liquid droplets in the outer cavity zone. A High-Speed Photography method, called “Sudoku”, with eight shooting windows was employed to capture the liquid flow of different zones in imaging experiments. Simulation results of liquid droplet velocity agreed well with the experimental results within a deviation of ±10%. This CFD simulation assisted with Sudoku Photography was helpful to comprehensively understand the liquid flow in the outer cavity zone of the RPB rea...

the dynamic development of the muzzle imprint by contact gunshot High Speed documentation utilizing the skin skull brain model
Forensic Science International, 2002Co-Authors: Michael J Thali, Beat P Kneubuehl, Richard Dirnhofer, Ulrich ZollingerAbstract:Abstract Many contact gunshots produce a muzzle imprint in the skin of the victim. Different mechanisms have been discussed in literature as being responsible for the creation of the muzzle imprint. Experimenting upon the synthetic non biological skin–skull–brain model, our goal was to document and study the creation of the muzzle imprint with the aid of High-Speed Photography. In our experiments, we could document with our High-Speed Photography (at exposure rates in the range of nanoseconds) the bulging, the pressing against the muzzle, and the splitting of the artificial skin. Furthermore, it was possible to photographically record the back pattern of synthetic tissue particles. And, the soot and gunpowder cavity could be reproduced experimentally. In conclusion the experiments completed with the skin–skull–brain model, using High-Speed Photography for documentation, show the promising possibilities of experimental ballistics with body models.

a study of the morphology of gunshot entrance wounds in connection with their dynamic creation utilizing the skin skull brain model
Forensic Science International, 2002Co-Authors: Michael J Thali, Beat P Kneubuehl, Ulrich Zollinger, Richard DirnhoferAbstract:The goal of this study was to document the dynamic effects created within, and the developing mechanisms of a gunshot entrance wound to the skin utilizing High-Speed Photography and the ‘‘skin–skull–brain model’’. The High-Speed Photography was taken with an Imacon 468/Hadland-Photonics camera. Full metal jacketed, 9 mm Luger projectiles were fired at the target model from a distance of 10 m. During the evaluation of the ‘‘skin–skull–brain model’’, it was possible to show that injuries inflicted to this model are fully comparable to the morphology of equivalent real gunshot entrance wounds. It has been possible to document and study the dynamic process of the ‘‘bullet–skin-interaction’’ in the gunshot entrance wound. The development of the morphologic terms of the entrance wound are discussed. In combination with High-Speed Photography, this ‘‘skin–skull– brain model’’ is a perfect tool for the documentation and the study of the dynamic development of gunshot entrance wounds in the skin. # 2002 Elsevier Science Ireland Ltd.
