Understanding particle detachment from surfaces is necessary to better characterize dust generation and entrainment. Previous work has studied the detachment of particles from flat surfaces. The present work generalizes this to investigate the aerodynamics of a particle attached to various locations on a model hill. The present work serves as a mod...

Insect wings are formed by intricate combinations of flexible membranes and rigid veins; such a structure enables excellent flight performance, adaptability to aerodynamic forces, and biological functions. Comprehensive understanding of the interplay between wing patterning and flight dynamics has however not been achieved yet due to enormous varia...

The historic city center of Amsterdam is full of monumental buildings, most of which are dwellings up to 400 years old. Many lives have been lived there, and consequently many alterations have been made. Restoring a canal house is therefore an exercise in reading the past while simultaneously considering the present. Each aspect can require a diffe...

The present paper introduces a mathematical model applicable to force and torque prediction on a rudder in behind hull/propeller conditions for a ship performing manoeuvres in a harbour. The latter implies a full 360 degrees possible inflow direction to the rudder, combined with propeller rates ahead or astern. The mathematical model coefficients w...

This review attempts to elucidate the physical origin of aerodynamic lift of an airfoil using simple formulations and notations, particularly focusing on the critical effect of the fluid viscosity. The evolutionary development of the lift problem of a flat-plate airfoil is reviewed as a canonical case from the classical inviscid circulation theory ...

Accurately predicting the lift and the drag exerted on aircraft has always remained essential for the designer. In order to develop the future commercial aircraft that minimize fuel burn and hence operating costs and environmental footprint, the designer needs to clearly identify the phenomenological sources of lift and drag. This is done by means ...

La capture d’objets sur une surface solide dans un écoulement laminaire est impliquée dans de nombreuses applications, notamment en bioanalyse et en recherche biologique. Etudié depuis le début du 20ème siècle, cette capture fait intervenir trois mécanismes : convection de l’objet par le liquide au-dessus de la surface captatrice, diffusion de l’ob...

We all have in mind Einstein's famous thought experiment in the elevator where we observe the free fall of a body and then the trajectory of a light ray. Simply here, in addition to the qualitative aspect, we carry out the exact calculation. We consider a uniformly accelerated reference frame in rectilinear translation and we show that the trajecto...

Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has...
