Controlling struvite particles’ size using the up-flow velocity
Chemical Engineering Journal, 2016 Struvite crystallization has been widely investigated, but little attention has been focused on particle size, an important characteristic in fertilizers that affects the agronomic response.

In recent years, a new method to measure transverse blood flow, based on the decorrelation of the radio frequency (RF) signals has been developed. In this paper, we investigated the influence of nonuniform flow on the velocity estimation. The decorrelation characteristics of transverse blood flow using an intravascular ultrasound (IVUS) array catheter ...

A flow-sensing velocity microphone
2019 IEEE SENSORS, 2019A microphone is described having a sensing element driven by viscous forces due to the fluctuating velocity of the air in a sound field. Unlike typical microphones having pressure-sensing diaphragm, thin microfabricated beams or thin porous plates are used to detect acoustic flow.

Velocity distribution in aortic flow
Cardiovascular Research, 1973Velocity measurements in the dog aorta using a thin film anemometer are described. The instantaneous velocity profiles for the ascending and descending aorta indicate a large inertial core region with relatively thin boundary layers; pronounced non-uniformities are present in the ascending aorta.

``Brillouin Flow'' with Thermal Velocities
Journal of Applied Physics, 1953A type of electron flow in a constant magnetic field is described. The beam of electrons is supposed to be everywhere in thermal equilibrium and the usual Brillouin flow is found when the equilibrium temperature tends to zero. Some considerations are put forward bearing on the choice of a suitable beam temperature in specific problems.

In recent years, a new method to measure transverse blood flow, based on the decorrelation of the radio frequency (RF) signals has been introduced. We investigated the decorrelation characteristics of transverse blood flow using an intravascular ultrasound (IVUS) array catheter by means of computer modeling.
