The ability to use microfluidic systems to fractionate a mixture of suspended particles based on their shape could lead to important applications. In the case of bioparticles, for example, shape is an important factor used to identify and characterize them. In fact, cell morphology has long been used in clinical diagnosis and it is also a marker of cell cycle (Sugaya et al. 2011; Beech et al. 2...

The oblique collision of two unequal-sized liquid droplets in a gaseous environment is investigated numerically. It found that the asymmetry flow field arising due to and greatly alters outcomes observed case head-on identical droplets. Our results reveal permanent coalescence occurs at intermediate angles, but large-angle collisions result reflexive separation stretching separation, respective...

To study the influence law of overburden rotating plate mechanism on fragmentation and separation potato soil agglomerates, a single-factor test response surface simulation analysis process were conducted in EDEM 2022 software. The results show that triangular rack blade overburdened has best effect separation. With increase lower speed, upper lift chain bar line tilt angle mechanism, agglomera...

flow passing through lateral intakes and channel junctions is turbulent. sediment flow and bed forms areaffected by these flow patterns and vice versa. in this research, a laboratory study was carried out toexplore a possible method for sediment control for a set of submerged vanes and a single spur dikesimultaneously. since a larger portion of the near-bed flow was diverted, the intake receive...

The goal of this work is to develop low order dynamical systems models for the unsteady aerodynamic forces on small wings and to better understand the physical characteristics of unsteady laminar separation. Reduced order models for a fixed, high angle of attack flat plate are obtained through Galerkin projection of the governing Navier-Stokes equations onto POD modes. Projected models are comp...

The multi-step error separation technique is a important method of roundness error separation, but it is not suitable to be used in measuring online for multiple inversion of tested parts, long measurement period and vulnerable to surroundings in the implementation process. In this paper, the studies of single-probe two-step error separation method have been realized by single sensor which is r...

Zero-net mass-flux jet based control of flow separation over a stalled airfoil is examined using numerical simulations. Two-dimensional simulations are carried out for a NACA 4418 airfoil at a chord Reynolds number of 40,000 and angle of attack of 18 deg. Results for the uncontrolled flow indicate the presence of three distinct natural time scales in the flow corresponding to the shear layer, s...

asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...

The separation of sources from an array of sensors is addressed in this paper. Based on the Kolmogorov's theorem, an adaptive algorithm is proposed to separate simultaneously all the unknown impinging sources on an aperture of sensors. This method solves the problem of simultaneous DOA (angle of arrival) estimation and source beamforming in narrowband array processing. The Kolmogorov's theorem ...

This study evaluated the effect of surface roughness and tapered angle of cone crowns on retentive force (RF). Cone crowns from Ti-6Al-7Nb alloy with a tapered angle of 4, 5, or 6° were fabricated using a milling machine and a finishing machine to produce a smooth surface. Cone crowns of 6° with a rough surface were also prepared. The RF during 1,000 cycles of insertion/separation was recorded....
