Turbulent entrainment in jets and plumes etc15 Tracking Number 493Presentation: Session: Jets and Wakes 2 Room: Room E Session start: 15:00 Tue 25 Aug 2015 Maarten van Reeuwijk m.vanreeuwijk@imperial.ac.uk Affifliation: Imperial College London John Craske john.craske07@imperial.ac.uk Affifliation: Imperial College London Topics: - Thermally driven turbulence, - Jets and wakes Abstract: We perform direct simulation of a statistically steady jets and plume and present the value of the entrainment coefficient decomposed into 1) turbulence production; 2) buoyancy effects; and 3) deviations from self-similarity. We explain theoretically how the two cases are linked and present a generalisation valid for forced and lazy plumes. |
