The goal is to understand the assumptions intrinsic to this simplified but commonly employed approach for the study of two-layer buoyancy reversing systems like the cloud-top mixing layer. Emphasis is placed on molecular transport phenomena. In particular, a formulation is proposed that recovers the actual nondiffusive liquid-phase continuum as a limiting case of differential diffusion. High-order numerical schemes suitable for direct numerical simulations in the compressible and Boussinesq limits are described, and simulations are presented to validate the incompressible approach. As expected, the Boussinesq approximation provides an accurate and efficient description of the flow on the scales (of the order of meters) that are considered.}, language = {en} } @misc{MelladoStevensSchmidtetal., author = {Mellado, Juan Pedro and Stevens, Bjorn and Schmidt, Heiko and Peters, Norbert}, title = {Buoyancy reversal in cloud-top mixing layers}, series = {Quarterly Journal of the Royal Meteorological Society}, volume = {135}, journal = {Quarterly Journal of the Royal Meteorological Society}, number = {641}, issn = {1477-870X}, doi = {10.1002/qj.417}, pages = {963 -- 978}, language = {en} } @misc{MaussKellerPeters, author = {Mauß, Fabian and Keller, D. and Peters, Norbert}, title = {A Lagrangian Simulation of Flamelet Extinction and Re-Ignition in Turbulent Jet Diffusion Flames}, series = {Symposium (International) on Combustion}, volume = {23}, journal = {Symposium (International) on Combustion}, number = {1}, issn = {0082-0784}, pages = {693 -- 698}, language = {en} } @misc{MaussSeshadriPetersetal., author = {Mauß, Fabian and Seshadri, K. and Peters, Norbert and Warnatz, J.}, title = {A Flamelet Calculation of Benzene Formation in Coflowing Laminar Diffusion Flames}, series = {Symposium (International) on Combustion}, volume = {23}, journal = {Symposium (International) on Combustion}, number = {1}, issn = {0082-0784}, pages = {559 -- 566}, language = {en} } @misc{MaussGoettgensPeters, author = {Mauß, Fabian and G{\"o}ttgens, J. and Peters, Norbert}, title = {Analytic Approximation of Burning Velocities and Flame Thickness of Lean Hydrogen, Methane, Ethylene, Acetylene and Propane Flames}, series = {Symposium (International) on Combustion}, volume = {24}, journal = {Symposium (International) on Combustion}, number = {1}, issn = {0082-0784}, pages = {129 -- 135}, language = {en} } @misc{BreitbachGoettgensMaussetal., author = {Breitbach, H. and G{\"o}ttgens, J. and Mauß, Fabian and Pitsch, H. and Peters, Norbert}, title = {Laminar Counterflow Mixing of Acetylene into Hot Combustion Products}, series = {Symposium (International) on Combustion}, volume = {25}, journal = {Symposium (International) on Combustion}, number = {1}, issn = {0082-0784}, pages = {1357 -- 1364}, language = {en} }
