You then set the number of particles (also known as the sprites on the screen), how large they are, how quickly they are generated, how fast they fall or rise (depending on your physics settings), and how long they remain onscreen before dying. With a particle system, you create a particle Emitter a point on the screen at which the particles will be generated. The overall image is of a gigantic, moving body of water, but if we break it down, that illusion of a moving shape of water actually consists of billions of individual particles. To simplify this concept, imagine you are watching a waterfall crashing onto the ground in front of you. Particle systems allow us to simulate physics-based effects and phenomena by using a collection of much smaller objects or sprites, which make up a larger whole image.
In this article, some of the particle systems and effects that Adobe After Effects offers will be covered. We'll also demonstrate just how particle systems operate in action.

This metric appears to be a good indicator of mobile-phase dispersion in ordered packed bed media, including overlapped beds, and is a useful tool for screening new stationary-phase morphologies without having to perform computationally expensive simulations. Finally, we introduce a metric to estimate column performance, the mean deviated velocity, a quantitative description of the spread of the velocity field in the column. Overlap is shown to decrease performance of ordered packed beds in all observed cases, thus we recommend it should be kept to the minimum extent necessary to ensure physical stability. In practice, ordered packed beds can only remain physically stable if the particles are fused to form a contiguous matrix, thus creating a positional overlap at the points of fusion between what would otherwise be discrete particles. Using computational fluid dynamics (Lattice Boltzmann Method) this work shows that nonspherical particles can both reduce mobile-phase band broadening and increase permeability compared with spheres in ordered packed beds. Although this has proven true for randomly packed beds in the past, we challenge this paradigm for ordered packings, the fabrication of which are now feasible through additive manufacturing (3D printing). Spherical particles are widely considered as the benchmark stationary phase for preparative and analytical chromatography.
