This book was released on 2018-10-25 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Boundary conditions to an existing large-eddy simulation model have been changed in order to simulate turbulence in the atmospheric boundary layer. Several options are now available, including the use of a surface energy balance. In addition, we compare convective boundary layer simulations with the Wangara and Minnesota field experiments as well as with other model results. We find excellent agreement of modelled mean profiles of wind and temperature with observations and good agreement for velocity variances. Neutral boundary simulation results are compared with theory and with previously used models. Agreement with theory is reasonable, while agreement with previous models is excellent.

Book excerpt: "Contains 80-plus selected--and reviewed--papers from the August 1996 symposium, held to examine the accomplishments and challenges posed by the rapid development of computational fluid dynamics as applied to the discipline of wind engineering. Summaries of the discussions, questions, and author responses are also included. Subjects addressed include aerodynamics of bluff bodies, bridges, vehicles, terrain, and buildings; structural response; air pollution; lab methodology and validation; and new computational schemes. An appendix lists abstracts of papers presented but not published. Keynote presentations cover current status and future trends in computational wind engineering (CWE); large eddy simulation of flow past a cubic obstacle; use of meteorological models in CWE; and past achievements and future challenges in CWE.
