Miscible displacement

  "id": "MLC-T-MET-007319",
  "term": "Miscible displacement",
  "field": "Meteorology and atmospheric science",
  "definition": "The movement of a fluid through a porous medium or another fluid, where the displacing fluid mixes completely with the displaced fluid at all proportions. This process eliminates the sharp interface that separates immiscible fluids, creating a transition zone of mixed composition. In atmospheric modeling, it describes how one air mass, such as a clean one, replaces a polluted one through mixing and advection, affecting pollutant concentration gradients.",
