This book presents a broad overview of the issues related to the flow of particles in suspensions. Chapters cover the newest research in advanced theoretical approaches and recent experimental techniques. Topics include macroscopic transport properties, the mechanics of capsules and cells, hydrodynamic ...
The present note is devoted to the problem of the interaction of two spherical particles in a steady uniform flow of a viscous incompressible fluid when the Reynolds number is not small. Asymptotic expressions are obtained for the interaction forces between the particles when the distances between ...
Second, we examine the dispersion of inertial micro-particles entrained by the turbulent flow. Specifically, we examine how the particle dispersion field evolves in the multiscale flow generated by the interactions between the large-scale structures, which are geometry dependent, with the smaller ...
The normalized concentration value of IJV-1 is lower than IJV-2, which is 0.266. The two schemes use the same ventilation method near the toilet. The hydrogen sulfide gas is distributed in the toilet stalls (Figure 8f). The flow lines in the middle area of the toilet are relatively dense...
7.3.2 New Fluid Flow Equations A porous medium can be defined as a multiphase material body (solid phase represented by solid grains of rock and void space represented by the pores between solid grains) characterized by two main features: that a REV can be determined for it, such that no ...
Consider first the case of a convergent nozzle shown in Figure 15.12, which examines a sequence of states a through c during which the back pressure is gradually lowered. For curve a, the flow throughout the nozzle is subsonic. As pB is lowered, the Mach number increases everywhere and the...
In this system, the rigidity of particles determines the symmetry of ordered states: long-lived, giant moving clusters are observed if particles strongly repel each other to prevent particle crossing, whereas large-scale nematic order emerges for particles which can slide past each other. We ...
Also, Parker Solar Probe's instruments might reveal the mechanisms at work behind the acceleration of solar energetic particles, which can reach speeds more than half as fast as the speed of light as they rocket away from the Sun. Such particles can interfere with satellite electronics, especiall...
In general, which state of matter has the lowest entropy? (a) Solid (b) Liquid (c) Gas (d) Plasma (e) Supercritical fluid Entropy: Entropy is a thermodynamic quantity that can be used to assess the level of disorder in a system. Ent...
Laufer's experiments, which were performed for NASA in the mid-1950s, concentrated on the fluctuating components of pipe flow; that is, ways to characterize and quantify the chaotic nature of the flow field through shear stress, turbulence intensities, correlation coefficient, spectrum analysis, and...
