three-dimensional cfd study of conical spouted beds

three-dimensional cfd study of conical spouted beds

Mar 15, 2017 · The flow behavior of conical spouted beds containing heavy particles that occurs in chemical vapor deposition (CVD) was investigated using the computational fluid dynamics (CFD) approach. A fully Eulerian description of solid and gas phases flows in 3D was used in these simulations. The hydrodynamics parameters including particle velocity, solid flux, and solid volume fraction profiles …
