Particle system — The term particle system refers to a computer graphics technique to simulate certain fuzzy phenomena, which are otherwise very hard to reproduce with conventional rendering techniques. Examples of such phenomena which are commonly replicated… … Wikipedia
Particle image velocimetry — (PIV) is an optical method used to measure velocities and related properties in fluids. The fluid is seeded with particles which, for the purposes of PIV, are generally assumed to faithfully follow the flow dynamics. It is the motion of these… … Wikipedia
Particle size (general) — Particle size is a notion introduced for comparing dimensions of solid particles ( flecks ), liquid particles ( droplets ), or gaseous particles ( bubbles ).The notion of particle size applies to *Colloidal particles; *Particles in ecology;… … Wikipedia
Particle statistics — refers to the particular description of particles in statistical mechanics. The three main types of particle statistics are:* For classical systems: Maxwell Boltzmann statistics (M B statistics)::ar{n} = frac{1}{e^{left(epsilon mu ight)/k T* For … Wikipedia

Particle collection in wet scrubbers — Wet scrubbers capture relatively small dust s with large liquid droplets. In most wet scrubbing systems, droplets produced are generally larger than 50 micrometres (in the 150 to 500 micrometres range). As a point of reference, human hair ranges… … Wikipedia
Particle beam — A particle beam is an accelerated stream of charged particles or neutrons (often moving at very near the speed of light) which may be directed by magnets and focused by electrostatic lenses, although they may also be self focusing (see… … Wikipedia
Systems of measurement — A system of measurement is a set of units which can be used to specify anything which can be measured and were historically important, regulated and defined because of trade and internal commerce. Scientifically, when later analyzed, some… … Wikipedia
