Dune Flow
Project: Thermopedia
Article: Gas-solid flows
Topics: Multiphase flows
Dune flow begins as the velocity is lowered and particles begin to settle out on the wall forming a dense flow region with a pattern like sand dunes. The velocity at which particles begin to settle out is called the saltation velocity.
