A large-eddy simulation study of water tunnel interference effects for a marine propeller in crashback mode of operation

Flow
Marine propellers are studied in design and off-design modes of operation like crashback, where the propeller rotates in reverse while the vehicle is in forward motion.

Wall shear stress generated by a Bernoulli pad: experiments and numerical simulations

Flow
Bernoulli pads generate locally large wall shear stresses on workpieces, which can be used for cleaning, but may also damage delicate surfaces. This work presents direct measurements of the wall shear stress using constant-temperature anemometry for the ...

Enhanced flow rate prediction of disturbed pipe flow using a shallow neural network

Flow
Trustworthy volumetric flow measurements are essential in many applications such as power plant controls or district heating systems. Flow metering under disturbed flow conditions, such as downstream of bends, is a challenge and leads to errors of up to ...

Fluid dynamics in the vitreous chamber during infusion in ophthalmic surgery: a numerical study

Flow
We numerically investigate the fluid dynamics of the infusion of balanced salt solution into the vitreous chamber during ophthalmic surgery. A 25-gauge vitrectomy set consisting of an infusion cannula and a vitreous cutter is inserted in a realistic ...

Formation of microfluidic droplets and jets in a solvent-rich oil phase

Flow
We develop original flow-based methods to interrogate and manipulate out-of-equilibrium behaviour of ternary fluids systems at the small scale. In particular, we examine droplet and jet formation of ternary fluid systems in coaxial microchannels when an ...

Turbulent boundary layer development over an air cavity

Flow
The turbulent boundary layer (TBL) development over an air cavity is experimentally studied using planar particle image velocimetry. The present flow, representative of those typically encountered in ship air lubrication, resembles the geometrical ...

Gravure printing with a shear-rate-dependent ink

Flow
Gravure printing is a type of printing method that uses metal cylinders with engraved cells that hold ink. The ink is transferred directly to the paper or other material by pressing it against the cylinder.
