The simulated particle size and side flow velocities ranged from 1.5 to 20 µm and 0 to 3 m/s, respectively.
Among physical variables, soil particle size has the highest correlation coefficient, followed by porosity of the soil media, bacterial size and flow velocity.
Unlike color Doppler sonography, modern techniques for contrast-enhanced ultrasound permit the measurement of tissue perfusion irrespective of vessel size or flow velocity.
The sorption or attachment of nanoparticles to soil and aquifer materials depends on the surface chemistry (i.e., electrical charge) of soil and nanoparticles, groundwater chemistry (e.g., ionic strength, pH, and presence of natural organic matter), and hydrodynamic conditions (pore size, porosity, flow velocity, and degree of mixing or turbulence).
The aerosolisation process after impaction with a target wall was simulated and focuses mainly on the effects of four variables: carrier size, air flow velocities, impact velocities and impact angles.
A number of experimental conditions were tested in order to investigate the influence of grain size and horizontal flow velocity on transverse vertical dispersion in the capillary fringe.
The study was performed using two different particle geometries and three tube-to-particle diameter ratios (D/dp) to understand the effects of the shape and particle size on the flow velocity distribution.
A slurry pot erosion tester was used as the test apparatus and test parameters such as erodent size, erodent concentration, flow velocity and test solutions were varied to study their effect on erosion corrosion.
In this paper, an attempt has been made to model the water split behaviour in an inclined open rectangular channel, resembling the actual size and the flow velocity used by the mineral processing industries, based on the Prandtl's mixing length approach.
From the Doppler power spectrum of the intensity fluctuation or sometimes from the autocorrelation function, one can retrieve the structure and dynamics of the turbid medium, e.g., particle size [ 32– 35], flow velocity [ 36], and coagulation and rheology process parameters [ 37– 40].
