In the current research, numerical analysis was used to investigate flow behavior through axial jet-pump with various mixing chamber configurations (straight pipe and straight pipe-diffuser-straight pipe) in presence of inlet swirling its influence on pump performance. The effects introducing suction motive line, are numerically investigated. optimum swirl angle is found be 45o which yields max...
On the Axial Mixing and Segregation of Binary Solid Mixtures in a Horizontal Rotating Conical Vessel
Complex hydrodynamic behavior of circulating fluidized beds makes their scale-up very complicated. In particular, large-scale lateral solids segregation causes a complex two-phase flow pattern which influences significantly their pe$ormance. Lateral solids segregation has been attributed to direct collisional interactions between particles as well as to interaction between gas-phase eddies and ...
The dispersal of dissolved iron (DFe) from hydrothermal vents is poorly constrained. Combining field observations and a modeling hierarchy, we find the DFe Trans-Atlantic-Geotraverse vent site occurs predominantly in colloidal phase controlled by multiple physical processes. Enhanced mixing near seafloor transport through fracture zones at fine-scales interacts with wider ocean circulation to d...
The inner wall of the intestine has multiscale structures whose roles, beyond increase surface area for absorption, are yet to be discovered. In this study, mixing process in a human duodenum with circular folds, driven by segmentation contraction, was simulated using multiphysics model, making it possible track evolution level distributions and enabling quantitative evaluation structural role ...

In this paper we investigate mixing and transport in correspondence of a meandering jet. The large-scale flow field is a kinematically assigned streamfunction. Two basic mixing mechanisms are considered, first separately and then combined together: deterministic chaotic advection, induced by a time dependence of the flow, and turbulent diffusion, described by means of a stochastic model for par...
Axial length (AL) is a significant indicator of eyeball development, but reports on the overall status of axial development in congenital cataract (CC) patients and its relationship with patient demographics, such as age, sex, and laterality, are rare. We prospectively investigated the AL of 1,586 patients ≤ 18 years old and undergoing cataract surgery in China from January 2005 to December 201...
