Large-Eddy Simulation. Guidelines for Its Application to Planetary Boundary Layer Research
Abstract
After a review of the current status of turbulence and diffusion modeling in the planetary boundary layer (PBL) and engineering fluid mechanics, the Working Group on Large Eddy Simulation (LES) concluded that inherent uncertainty is a major complication to atmospheric experiments and modeling and that data bases for future models of PBL are unlikely to be derived from field experiments. The roles of LES in quantifying inherent uncertainty and in providing appropriate data bases for analysis are discussed. Long range guidelines for PBL research using LES are presented (I) for the technical components of a program--turbulence theory, computational problems and requirements, physical and numerical experiments and transfer of technology to less complex models--and (II) for the management program to simulate research in environmental fluid mechanics.
