Lagrangian study of transport and mixing in a mesoscale eddy street

open access: yes, 2011
We use dynamical systems approach and Lagrangian tools to study surface transport and mixing of water masses in a selected coastal region of the Japan Sea with moving mesoscale eddies associated with the Primorskoye Current.

Influence of Reaming While Drilling on the Circulation of Drilling Fluid

open access: yesShiyou jixie, 2019
The operation of reaming while drilling will have an impact on the circulation of drilling fluids, but there is still no relevant research in China. To address the problem, numerical simulation based on computational fluid dynamics was carried out to ...

Flow-Induced Vibration Stability in Pilot-Operated Control Valves with Nonlinear Fluid–Structure Interaction Analysis

open access: yesActuators
Control valves in nuclear systems operate under high-pressure differentials generating intense transient fluid forces that induce destructive structural vibrations, risking resonance and the valve stem fracture.

Diffusion maps embedding and transition matrix analysis of the large-scale flow structure in turbulent Rayleigh--B\'enard convection

open access: yes, 2019
By utilizing diffusion maps embedding and transition matrix analysis we investigate sparse temperature measurement time-series data from Rayleigh--B\'enard convection experiments in a cylindrical container of aspect ratio $\Gamma=D/L=0.5$ between its ...

Droplet migration in a Hele-Shaw cell: Effect of the lubrication film on the droplet dynamics

open access: yes, 2016
Droplet migration in a Hele--Shaw cell is a fundamental multiphase flow problem which is crucial for many microfluidics applications. We focus on the regime at low capillary number and three-dimensional direct numerical simulations are performed to ...

Investigation of the geothermal system in region of Selime (Turkey) by resistivity methods

open access: yesGeofísica Internacional
The Anatolian platform continues its development with highly complex tectonic activities in Central Anatolia, known as tectonic deformation. In addition to faulting due to the plate movements, the fluid dynamics in the underground and the thermal cycle ...

Integration of the subarachnoid space and lymphatics: Is it time to embrace a new concept of cerebrospinal fluid absorption?

open access: yesCerebrospinal Fluid Research, 2005
In most tissues and organs, the lymphatic circulation is responsible for the removal of interstitial protein and fluid but the parenchyma of the brain and spinal cord is devoid of lymphatic vessels.

Circulation of hydraulically ponded turbidity currents and the filling of continental slope minibasins

open access: yesNature Communications
Natural depressions on continental margins termed minibasins trap turbidity currents, a class of sediment-laden seafloor density driven flow. These currents are the primary downslope vectors for clastic sediment, particulate organic carbon, and ...
