Comparison of dns of compressible and incompressible turbulent droplet-laden heated channel flow with phase transition [PDF]

open access: yes, 2012
In this paper a turbulent channel flow with dispersed droplets is examined. The dispersed phase is allowed to have phase transition, which leads to heat and mass transfer between the phases, and correspondingly modulates turbulent flow properties.
