A single particle does not have the properties ... close Brownian motionThe random motion of microscopic particles suspended in a gas or liquid as a result of collisions. In this example, the ...

Modelling investigations are required to improve methods that apply turbulent fluctuations in the velocity field to the particle motion, as well as methods to resolve gas species concentrations on the ...

Regular OSCILLATION, for instance, by a particle in a solid, fluid or gas, displaced from its normal position or random motion, when the force required is proportional to the displacement. This motion ...
