Mueller, Physically-derived reduced-order manifold-based modeling for multi-modal turbulent combustion, Combustion and Flame () Abstract: Direct numerical simulation of a turbulent channel flow with heat transfer was performed at very low Reynolds numbers. Two different thermal boundary conditions were studied, and temperature was considered as a passive scalar. The computations were carried out with huge computational boxes (up to x 2 x in the streamwise, wall-normal, and spanwise directions, Cited by: 7.

Investigation of turbulent mixing in shallow lakes using temperature microstructure measurements Andreas Lorke Institute of Freshwater Ecology and Inland Fisheries, MueggelseedammD.
Direct determination of the irreversible turbulent flux of salinity in the ocean has not been possible because of the complexity of measuring salinity on the smallest scales over which it mixes.
A microstructure profiler was designed especially for the investigation of the diurnal dynamics of turbulent mixing in shallow lakes. 7 hours observation of these dynamics in a shallow, polymictic lake shows a multitude of different mixing processes acting together on very short time-scales.

It was found that (1) ∼% of the vertical wind energy flux P 10 (∼39 mW m −2), estimated 10 m above the lake surface, was available for turbulent mixing in the entire lake water body; (2) ∼% of P 10 was dissipated by turbulence in the weakly stratified surface layer (epilimnion ;6 m deep), and ∼% of P 10 reached the Cited by: Determination of vertical turbulent diffusivities of heat in a North Florida lake.

WARNER* and VRDAT S. ARPACIt (Received 19 April and in revised form 7 August ) Abstract-An experimental investigation of turbulent natural convection in air is described. For example, at low values of ε/νN 2, where ε is the dissipation of turbulent kinetic energy and ν is the kinematic viscosity, eddy diffusivities depend on the Schmidt number Sc = ν/D Φ (Barry et al.
