Abstract
In the present study transitional thermal plumes are examined by means of numerical simulations and experiments. The objective of the research is the determination whether a Large-Eddy Simulation can be applied in these cases and what subgrid scale model should be used. The Prandtl number is 5.82. Results are obtained in terms of the topology of a two dimensional slice of the temperature field and the local temperature and velocity as function of time. Experimentally the topology of the temperature field was obtained using liquid crystals suspended in water; the local temperature was measured with a thermocouple. Numerically, two-and three-dimensional calculations were performed, using the subgrid turbulent kinetic energy model, as used by Nieuwstadt [10], and the Smagorinsky [12] model. In the two dimensional case also direct numerical simulations were performed.
