= Preferential concentration
{wiki=Preferential_concentration}
Preferential concentration refers to a phenomenon in fluid dynamics and particle dynamics, particularly in suspensions and aerosols, where particles are not uniformly distributed throughout a flow. Instead, they tend to cluster or align preferentially in certain regions of the flow field, often in areas of low vorticity or high shear. This clustering can occur due to a variety of factors, including the interplay between the particles' inertial effects and the flow field's characteristics.
