The high-efficiency vortex (HEV) device used here as a direct-contact heat exchanger (DCHE) is a generic multifunctional exchanger/reactor in which wall tabs generate longitudinal vortices responsible for convective radial transfer that enhance macro-mixing, phase dispersion and fast temperature homogenization in the flow.
Two initial conditions were studied: (i) solid solution obtained by fast cooling after homogenization; and (ii) coarse Al2Cu precipitates obtained by a very slow cooling from the homogenization temperature.
It is assumed that consumption of low ozone dosages is faster than sample homogenization in the batch reactors used.
In addition to the possibility of achieving highly reproducible mixing conditions, these mixers enable a sensitive control of fast reactions, an efficient initial homogenization of educts and, consequently, a rapid buildup of supersaturation as the driving force for precipitation.
Besides low construction effort, these mixers enable a sensitive control of fast reactions, an efficient initial homogenization of educts and consequently a rapid build-up of supersaturation as the driving force for precipitation and crystallization.
A two-step homogenization procedure for fast non-linear static analyses of FRCM (Fabric Reinforced Cementitious Matrix) composites reinforced masonry walls in-plane loaded is presented and benchmarked on a series of FRCM strengthened tuff panels experimentally tested under diagonal compression at the University of Naples, Italy.
It highlights the fading building like a bit of false hope or lurid makeup, hinting at an encroaching future of fast-food emporiums or chain stores and the further homogenization of the already homogenized.
The mixing in the melting process and the subsequent solute trapping effect during fast solidification process result in the homogenization of elements in the melted layer.
Ultrasonic intensification (periodic ultrasonic treatment during the fermentation process) can result in a more effective homogenization of biomass and faster energy and mass transfer to biomass over short time periods which can result in enhanced microbial growth.
In all these mixers while homogenization in the direction of rotation is fast, mediated by a convective mixing process, mixing in the horizontal (axial) direction, driven by a dispersive process, is often much slower.
There are three regimes depending on how fast the intensity of the noise goes to zero relative to homogenization parameter.
