Eulerian and Lagrangian approaches to multi-dimensional condensation and collection

by Xiang-Yu Li, A. Brandenburg, N. E. L. Haugen, and G. Svensson

  • Eulerian Smoluchowski and Lagrangian superdroplet/superparticle approaches to cloud droplet growth through condensation and collection are compared using DNS techniques
  • Size spectra agree well for both approaches, especially in case of turbulence
  • The Lagrangian scheme with symmetric collection is found to be optimal and compu- 19 tationally most efficient
