Center for Turbulence Research Summer Program

该项目将部分支付受邀演讲者和学生参与者的旅费，以及将在斯坦福大学举行的名为“湍流研究中心暑期项目”的研讨会的组织费用。一个竞争性的过程被用来选择参与者，基于他们的研究建议的优点和他们的研究证书。部分资金将用于支持第18、19和20届两年一度的CTR暑期项目。2020年项目暂定于2020年7月19日至8月14日在斯坦福大学举行。支持CTR暑期项目的其他政府机构有ONR、AFOSR、NASA和DOE。2020年，我们计划将参赛人数限制在60人以内。在每个版本中，CTR暑期项目通常会吸引来自斯坦福大学以外的70名参与者，他们与大约30名斯坦福大学的参与者一起进行为期一个月的湍流物理和建模相关项目的深入研究。斯坦福大学的参与者包括教职员工、研究生和一个由10-20名CTR博士后组成的团队，他们协助全职访客，以保证每个研究项目的成功成果。在2018年的暑期项目中，CTR接待了来自8个国家的74名参与者，其中包括26个美国机构。38名CTR工作人员与参与者一起工作，并在暑期项目期间为36个研究项目做出了贡献。参与者包括实验学家、理论家和计算科学家。采用竞争性程序来选择参与者。他们的选择是基于他们的研究资质、他们的研究建议的优点以及与CTR感兴趣的领域的相关性。研究生被接受陪同他们的研究顾问。以津贴的形式向参加者提供财政支持。研讨会的主要目标之一是确定未来几年湍流建模的挑战。该项目的调查结果将被收集并作为一份综合技术报告发表。预计该报告将包括40至50篇技术论文（约500页），这些论文将交付给NSF和该计划的其他赞助者，并在日历年年底在全球范围内传播。该报告与以前讲习班的报告一样，将在全球网络（http://www.stanford.edu/group/ctr/）上提供。报告中的许多论文最终将在高质量的技术期刊上发表。CTR暑期项目的大部分内容包括对数值模拟数据库的实际操作，以测试参与者提出的模型和假设。产生新数据库的额外计算可能在夏季进行。参与者根据他们提出的研究领域被分成焦点小组。在2018年夏季项目中，焦点小组包括多相流，数值方法，多物理场和数据驱动研究，壁面湍流和燃烧。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The project will partially cover travel expenses of invited speakers and student participants and organizing expenses related to the workshop entitled "The Center for Turbulence Research Summer Program," to be held at Stanford University. A competitive process is used to select the participants, based on the merits of their research proposals and their research credentials. Partial funding will support the eighteenth, nineteenth, and twentieth biennial CTR Summer Programs. The 2020 Program is tentatively scheduled to be held at Stanford from July 19 to August 14, 2020. The other government agencies that support the CTR Summer Programs are ONR, AFOSR, NASA, and DOE. For 2020 we plan to limit the number of participants to no more than 60. In every edition, the CTR Summer Programs have typically engaged up to 70 participants from outside of Stanford, who join about 30 Stanford participants for a one-month period of intense research on projects related to turbulent flow physics and modeling. Stanford participants include faculty, graduate students, and a cadre of 10-20 CTR postdocs that participate assisting full-time the visitors in order to warrant successful outcomes in every research project. In 2018 Summer Program, CTR hosted 74 participants from 8 countries, including 26 U.S. institutions. Thirty-eight CTR staff members, worked alongside the participants and contributed to 36 research projects spearheaded during the Summer Program. The participants included experimentalists, theoreticians, and computational scientists. A competitive process is used to select the participants. They are selected based on their research credentials, the merits of their research proposals and the relevance to areas of interest to CTR. Graduate students are accepted to accompany their research advisors. Financial support in the form of stipends is provided to the participants. One of the main goals of the workshop is to frame the challenges in turbulence modeling for the next few years. The findings of the program will be collected and published as a comprehensive technical report. It is expected that the report will consist of forty to fifty technical papers (about 500 pages) which will be delivered to NSF and to other sponsors of the program, in addition to worldwide dissemination at the end of the calendar year. The report, like the reports from the prior workshops, will be available on the worldwide web (http://www.stanford.edu/group/ctr/). Many of the papers in the report will be eventually published in high quality technical journals. The bulk of the CTR Summer Programs involves hands-on interrogation of numerical simulation databases for testing models and hypotheses proposed by the participants. Additional calculations to generate new databases may be performed during the summer. The participants are divided into focus groups based on their proposed areas of research. In the 2018 Summer Program, the focus groups consisted of Multi-phase Flows, Numerical Methods, Multi-physics and Data-driven Studies, Wall Turbulence, and Combustion.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
