Titre de série : Journal of applied physics, Vol.39 No.11 Titre : The collision parameter coalescence and disruption of water droplets Type de document : articles et extraits Auteurs : J. R. Adam, Auteur ; C. D. Hendricks, Auteur ; N. R. Lindblad, Auteur Année de publication : 1968 Importance : p.5173-5180 Langues : Français (fre) Résumé : Using free pairs of droplets in the size range from 60 to 500 mu in radius, the effects of charge, velocity, and impact parameter on the collision and the disruption of droplets have been examined. The impact parameters for collision and disruption of 300 and 60 mu radius droplets over a charge range from 10-15 to 10-12 C per droplet, and with impact velocity from 1 to 8 m/sec are reported. It is found that for droplets in this size and velocity range, electric charge on the droplets has no appreciable effect on the collision and coalescence process. However, the impact velocity and the impact parameter of the droplets dramatically affect the stability of the coalesced droplet. For 60 mu droplets, all collisions coalesce and form one droplet if the impact velocity is less than 2.2 m/sec. As the impact velocity is increased, the impact parameter for which only one droplet is produced after collision decreases and all the other collisions disrupt into several droplet fragments. For impact velocities greater than 8 m/sec, no collisions are stable

Schimschak, Auteur ; J. Krug, Auteur Année de publication : 2000 Importance : p.695-703 ISBN/ISSN/EAN : 0021-8979 Langues : Français (fre) Résumé : We present a detailed numerical study of the electromigration-induced shape evolution of quasi-two-dimensional (cylindrical) voids in metallic thin films. The problem is treated within a continuum formulation which takes into account mass transport along surfaces, current crowding, and crystal anisotropy in the surface mobility. Finite strips with periodic boundary conditions in the current direction are treated as well as voids in infinite or semi-infinite films. For the strip geometry, it is shown that the linear instability of the strip edge can induce the release of voids into the interior of the film, while edge voids develop into fatal slits only in the presence of moderate (not too strong) crystalline anisotropy. Distorted voids in an infinite film typically disintegrate, but the breakup scenario is qualitatively different in isotropic and anisotropic media. A rigid boundary attracts voids and may also induce void breakup.

Titre de série : Journal of applied physics, Vol.52 No.3 Titre : Influence of particle interaction on coercivity and squareness of thin film recording media Type de document : articles et extraits Auteurs : R. F. Soohoo, Auteur Année de publication : 1981 Importance : p.2459-2461 Langues : Français (fre) Résumé : Digital Recording density in continuous thin films can be significantly larger than in conventional particulate media. For this reason, there is much active research and development in such thin film recording media at present. However, no detailed calculation leading to a satisfactory explanation for the high squareness and an Hc decreasing monotonically with film thickness t has appeared. Using a model of strongly interacting anisotropic grains and neglecting exchange at grain boundaries, we examined here particle interaction and its influence on S and Hc. It is shown that the rather high squareness found in such media (e.g., S?0.8 for films of Co with t200Å) is related to strong dipolar interaction between the constituent grains. Although such films are continuous, surface roughness due to microscopic film thickness variation from grain to grain-boundary can be appreciable. Indeed, our calculation shows that these thickness variations can account for Hc and its variation with t experimentally observed.

Titre de série : Journal of applied physics, Vol.59 No.4 Titre : The statistical self-similarity hypothesis in grain growth and particle coarsening Type de document : articles et extraits Auteurs : W. W. Mullins, Auteur Année de publication : 1986 Importance : p.1341-1349 ISBN/ISSN/EAN : 0021-8979 Langues : Français (fre) Résumé : The time dependence of particle size (e.g., mean volume) in normal grain growth, bubble growth, and late-stage coarsening is deduced from a statistical self-similarity (SSS) hypothesis, according to which consecutive configurations of the system in the self-similar mode are geometrically similar in a statistical sense, and from the scaling characteristic of v-dot, the rate of change of the volume of a given particle. It is shown that if v-dot scales as v-bar alpha under uniform magnification, where v-bar is the mean particle volume and alpha a constant depending on the controlling kinetics and geometry of the system, then v-bar 1–alpha is a linear function of the time. Values of alpha are obtained for a number of cases. The treatment is free of many of the approximations and geometrical simplifications used in most theories. Evidence for the SSS hypothesis is discussed. Special new results are obtained for two-dimensional bubble and idealized grain growth that should be testable by computer simulation or by observation of a well-behaved soap-bubble array.

Résumé : The time dependence of particle size (e.g., mean volume) in normal grain growth, bubble growth, and late-stage coarsening is deduced from a statistical self-similarity (SSS) hypothesis, according to which consecutive configurations of the system in the self-similar mode are geometrically similar in a statistical sense, and from the scaling characteristic of v-dot, the rate of change of the volume of a given particle. It is shown that if v-dot scales as v-bar alpha under uniform magnification, where v-bar is the mean particle volume and alpha a constant depending on the controlling kinetics and geometry of the system, then v-bar 1–alpha is a linear function of the time. Values of alpha are obtained for a number of cases. The treatment is free of many of the approximations and geometrical simplifications used in most theories. Evidence for the SSS hypothesis is discussed. Special new results are obtained for two-dimensional bubble and idealized grain growth that should be testable by computer simulation or by observation of a well-behaved soap-bubble array.

A 2D foam chamber was designed and constructed, which allows long-term video recordings to be made. The bubbles corresponding to the last six frames, when the so-called scaling state is attained, were digitized at equally spaced time intervals, to measure their surface and count their number of neighbors.

Then, except for the degenerate case of simple conductive decay, stationary fluctuation fields are postulated. Largely by dimensional reasoning and some simple postulates, forms of the temperature fluctuation power spectrum for particular wave number ranges are deduced and are compared with the results of previous analyses giving corresponding segments of the velocity spectrum.

May, Auteur Année de publication : 1952 Importance : p.1362-1372 Langues : Français (fre) Résumé : Investigations, carried out principally on the vertical water entry of steel spheres, are described. Graphs show the effect of several experimental parameters on the time and place of occurrence of various events in the life of the cavity which accompanies the entry. These parameters include the density and pressure of the atmosphere above the water, and the velocity, size, and nose shape of the missile. Froude-scaling is found to be a good first approximation in describing cavity behavior, and some improvement is effected by the pressure-density scaling of the atmosphere above the water. The energy lost by a missile during the open-cavity phase of its water entry is found to be used up principally in the formation of the cavity, and the cavity shape is not dependent on the nose shape of the missile for a given drag force. ©1952 The American Institute of Physics

A mat is modeled by randomly depositing thin linear-elastic fibers on top of each other under the influence of an external pressure. The external pressure has the effect of bending the fibers over each other. The fibers are assumed rigidly bonded at contacts. For a low external pressure the stiffness of the mat deviates from that of its two-dimensional projection only by a geometrical factor, and the effective Poisson contraction is close to zero. For higher pressures, stiffness is governed by two competing effects and a maximum appears in the stiffness. The effective Poisson ratio is clearly negative in this range. An approximative analytical description is developed for the stiffness of mats formed under low external pressure. The stiffness is given as a function of only a few parameters: the degree of bonding, the dimensions of the fibers, the elastic constants of the fiber material, and the density of fibers.
