Hydrodynamic performance of a vortex generator [PDF]
Abstract The performance of a vortex generator intended for a marine application is investigated experimentally in a cavitation tunnel. Several tests were made as a preliminary study to gain basic knowledge of an initial design concept. Investigations included flow visualisation of local flow and wake trajectory, cavitation inception and occurrence ...

Efficiency of Fish Propulsion [PDF]
It is shown that the system efficiency of a self-propelled flexible body is ill-defined unless one considers the concept of quasi-propulsive efficiency, defined as the ratio of the power needed to tow a body in rigid-straight condition over the power it ...

High-performance computing in water resources hydrodynamics [PDF]
Abstract This work presents a vision of future water resources hydrodynamics codes that can fully utilize the strengths of modern high-performance computing (HPC). The advances to computing power, formerly driven by the improvement of central processing unit processors, now focus on parallel computing and, in particular, the use of ...

Nanotechnology to Improve the Performances of Hydrodynamic Surfaces [PDF]
Nature continues to inspire scientists to adapt solutions in order to satisfy human needs, mainly in the maritime domain with metallic surface corrosion and its mechanical friction. In this research, the source of innovation comes from the lotus leaf and its well-known super-hydrophobicity.

Hydrodynamic performance and heat generation by centrifugal pumps [PDF]
For over a century, centrifugal pumps (CP) have been used in various applications, from large industrial pumps to flow pumps for aquariums. However, the use of CP as blood pumps has a rather short history. Consequently, the hydraulic performance data for a blood CP are limited.

A Simulation Method to Resolve Hydrodynamic Interactions in Colloidal Dispersions [PDF]
A new computational method is presented to resolve hydrodynamic interactions acting on solid particles immersed in incompressible host fluids. In this method, boundaries between solid particles and host fluids are replaced with a continuous interface by ...

Electro-hydrodynamic synchronization of piezoelectric flags
Hydrodynamic coupling of flexible flags in axial flows may profoundly influence their flapping dynamics, in particular driving their synchronization. This work investigates the effect of such coupling on the harvesting efficiency of coupled piezoelectric

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...
