The flow around a circular arc is governed by the effect of sharp leading edge and arc's curvature. There range incidences where leading-edge separation bubble (LESB) formed on convex side arc, reattached boundary layer separates further downstream. Akin to foils cylinders, for increasing values Reynolds number, turns from laminar turbulent resulting in step change forces, here termed force cri...

Against the background of a drastically increased demand marine proteins, off-bottom, bivalve aquaculture, provides significant potential for production growth when moved into more energetic waters. Hence, research, industry and politics are currently proposing development new offshore sites. The highly conditions at these sites present challenging environment aquaculture. In this work, physica...

Recently, several experimental and numerical studies have underlined the advantages of adding clumped weights at discrete positions mooring lines. To confirm influence these weights, an study was performed for a 1:30 scale model line. In this study, weight is modeled as scaled disc placed different along The series experiments has been carried out CEHIPAR towing tank using submerged studless ch...

The Gate Rudder is a recently introduced twin rudder system whose major advantages stem from its energy-saving properties. two foil-shaped blades of the rudder, placed aside propeller, act as partial duct in wake hull producing additional thrust. However, since primary safety device on any vessel, investigating manoeuvrability performance critical aspect that needs careful and detailed consider...

The high-speed motion of a seaplane involves the coupled hydrodynamic and aerodynamic effects. suction force, pressure, free surface model were numerically investigated to understand characteristics seaplane's planing motion. study utilized SST-DDES turbulence analyse Overset mesh method rigid body employed simulate substantial seaplane. volume fluid (VOF) was used capture sharpen interface bet...

We introduce an application of self-driving vehicle technology to the problem of towing aircraft at busy airports from gate to runway and runway to gate. Autonomous towing can be supervised by human rampor ATC controllers, pilots, or ground crew. The controllers provide route information to the tugs, assisted by an automated route planning system. The planning system and tower and ground contro...

The paper presents velocity measurements, using particle image velocimetry, as well a reconstruction of hydrodynamic pressures for the analysis fast ships. Stereoscopic PIV measurements with towed underwater system are conducted during towing tank tests to obtain field in bow region ship at speeds up Fr=0.8. While model is kept fixed trim and sinkage, multi-plane total 68 measurement planes rec...

What a change in situation... A few years ago, at the height of the amyloid cascade, tau biologists, (so called Tauists) were virtually invisible in Alzheimer’s disease conferences, which were occupied by amyloid biologists (so called baptists). Currently, sessions dedicated to tau and Tauopathies are increasing in several congresses on neurodegenerative diseases, including AAIC and AD/PD. Inte...
