Dust settling is a research area focused on the study of how fine particles, such as dust or sediment, settle out of a fluid or gas medium. This phenomenon is important in a variety of industries and environmental processes, including air pollution control, sediment transport in rivers and streams, and the deposition of dust on surfaces. Researchers study the factors that influence dust settling, such as particle size, shape, density, and the properties of the medium in which the particles are suspended. Understanding dust settling can help improve air quality, prevent erosion, and optimize industrial processes.
