Mathematical Modeling of Patient-Specific Ventricular Assist Device Implantation to Reduce Particulate Embolization Rate to Cerebral Vessels
I. Ricardo Argueta-Morales,Reginald Tran,Andres Ceballos,William Clark,Ruben Osorio,Eduardo Divo,Eduardo Divo,Alain J. Kassab,William M. DeCampli,William M. DeCampli +9 more
TL;DR: In this computational model, the percentage of particles entering the cerebral vessels from a VAD-OG is reduced by nearly 60% by optimizing outflow-graft configuration and ascending aorta recirculation zones, which may be thrombogenic, can be eliminated.

Nasal Structural and Aerodynamic Features That May Benefit Normal Olfactory Sensitivity.
Chengyu Li,Jianbo Jiang,Kanghyun Kim,Bradley A. Otto,Alexander A. Farag,Beverly J. Cowart,Beverly J. Cowart,Edmund A. Pribitkin,Pamela Dalton,Kai Zhao +9 more
TL;DR: It is revealed that nasal anatomy and aerodynamics might have a significant impact on normal olfactory sensitivity, with greater airflow vortex and a narrower vestibule region likely intensifying the airflow vortex toward the Olfactory region and resulting in greater olfaction sensitivity to high mucosal soluble odors.

TL;DR: In this paper, the influence of the cloud turbulence on the dust segregation and fragmentation through a study combining both, experimental and computational approaches was described, and the behavior of the gas-solid mixture evidenced with the standard rebound nozzle was compared with that observed with six new nozzle geometries.
Evaluation of an Incompressible Energy-Vorticity Turbulence Model for Fully Rough Pipe Flow
TL;DR: Evaluation of an Incompressible Energy-Vorticity Turbulence Model for Fully Rough Pipe Flow is presented in this paper, where the model is extended to include a fully rough pipe flow.
Journal ArticleDOI
Energy–Vorticity Turbulence Model with Application to Flow Near Rough Surfaces
TL;DR: In this paper, a more direct analogy between turbulent and molecular transport is presented for an energy-vorticity turbulence model, which relates the eddy viscosity to a mean vortex wavelength associated with the larger eddies primarily responsible for turbulent transport.

Similarity structure of vorticity fluctuation and the theory of turbulence
TL;DR: In this paper, it is shown that by neglecting the terms in viscosity in the equations of vorticity fluctuation in the moving system, the condition of dynamical similarity leads to von Karman's well-known similarity relations for flows limited by a boundary and in the central regions of the wakes, while in the outer region within the wake interior, where the effect of viscosities can not be ignored, the similarity condition yields the experimentally established relation that the Reynolds apparent shearing stress component is proportional to the transversal gradient of the velocity of the
