Technical Session Tracks

Presentations on all topics related to Computational Wind Engineering are being solicited. Topics are being grouped into a Track/Topic which is listed for selection as part of the abstract submittal. Technical Sessions will be organized within a Track/Topic.  A few special sessions within some of the Track/Topics have already been initiated and specified below.  The CWE2010 program will have several parallel Track/Topics arranged to minimize conflicts for attendees’ participation.

Track/Topic: Select preferred Track/Topic from the list below when submitting your abstract. The descriptive text is provided here as guidance. When you submit your abstract, please specify in the Notes box the title of any preferred special session listed within a track. See  Special Session for additional descriptions.

1. CWE applications for homeland/societal security including natural and human-caused hazards and disasters
Presentations to follow Plenary Session entitled, “Applying Computational Wind Engineering to Practice: Perspectives from the Political, Academic, Corporate and Public Sector Community,” on Monday, May 24, cover the wide range (from wind hazards to wind energy) of computational models linked to present and future topic applications. The key element of presentations for this session compared to the topic sessions below is that they should represent integrated application with relevant endpoints with public policy implications. The perspective of presentations can be as the applications engineer, policy developer, or client. Where there is sufficient interest, sessions will be organized with association as wind engineering, insurance industry, governmental policy, emergency planner or responder, professional associations, university scholars, and other proposed.

Presentations by both wind engineers and computer scientists to follow Plenary Session entitled, “Trends in High Performance Computing for Wind Engineering,” on Tuesday, May 25, cover projects including discussions and applications especially linked to future computing for wind engineering applications. If there is sufficient interest, a special open session will be organized for CFD developers of public domain software (both commercial licensed and open-source) to provide a non-commercial response to a set of questions and present their views on trends in computing and their software. Interested CFD developers should contact CWE2010 Chairperson Alan Huber alan.huber@cwe2010.org before submitting an abstract.
