  "term": "Stokes number",
  "field": "Chemistry",
  "definition": "A dimensionless quantity representing the ratio of the stopping distance of a particle to a characteristic dimension of an obstacle in a fluid. It characterizes the behavior of an aerosol particle in a non-uniform gas flow. A very small Stokes number indicates the particle follows the fluid flow, while a large number indicates the particle continues on its original path due to inertia.",
