Wind Tunnel Pressure Measurements on Small-Scale Buildings and their Components

申请者西奥多·斯塔索普洛斯教授于20世纪80年代初设计并建立了安装在康科迪亚大学建筑空气动力学实验室的边界层风洞。自成立以来，风洞已被用于研究所有风与建筑物的相互作用，如确定建筑物上的风压、评估建筑物结构周围的风环境、评估建筑物排放的污染物的扩散、建筑物内的通风以及城市环境中所有与风有关的问题，包括评估风能潜力。申请人将研究重点放在风对建筑物影响的评估上，并为提高对建筑物的基本认识作出了贡献。这项研究的成果显然参与了包括加拿大国家建筑规范(NBCC)在内的不同国家的风标准和实践守则的制定。*申请人渴望升级现有的压力测量系统(DSM/ZOC系统)，用于康科迪亚大学边界层风洞实验室的风荷载测量。所要求的研究工具和仪器包括四个MPS 4264(微型压力扫描仪)及其安装附件。与目前的ZOC33/DSM34000系统相比，使用MPS 4264有许多好处，这将克服几个正在进行的研究项目所需的进行风洞实验的技术限制。这些研究在评估建筑物及其部件(太阳能电池板、天篷、竖挺、阳台等)上的风荷载方面是新颖的。风能建筑规范和标准正在急切地等待这些特定研究的研究结果，以产生相关的设计规定。此外，相关学生论文所要求的进展在很大程度上取决于风压测量仪器的升级，从而能够继续进行风洞实验研究。有必要指出的是，研究生可以很容易地掌握MPS 4264，并可以随时了解研究数据的收集和可追溯性。*所需的仪器将从ScaniValve公司购买，总成本为130,557美元。**

The applicant, Prof. Theodore Stathopoulos, has designed and established Boundary Layer Wind Tunnel installed in the Building Aerodynamics Laboratory of Concordia University in early 1980s. Since its establishment, the wind tunnel has been used for the study of all wind-building interactions such as the determination of wind pressures on buildings, the assessment of wind environment around building configurations, the evaluation of dispersion of pollutants emitted from buildings, the ventilation in buildings and all wind-related issues in the urban environment including evaluation of wind energy potential. The applicant has focused his research on the assessment of wind effects on buildings and has contributed to the improvement of their fundamental understanding. The outcome of this research has been clearly involved in the development of provisions of wind standards and codes of practice of different countries including the National Building Code of Canada (NBCC).******The applicant aspires to upgrading the existing pressure measuring system (DSM/ZOC system) used for wind loading measurements in the boundary layer wind tunnel laboratory of Concordia University. The research tool and instrument requested consists of four units of MPS 4264 (Miniature Pressure Scanner) and their accessories for setup. There are many benefits in using the MPS 4264 over the current ZOC33/DSM34000 system that will overcome the technical limitations for conducting wind tunnel experiments required for several ongoing research projects. These research studies are novel in the evaluation of wind loads on buildings and their components (solar panels, canopies, mullions, balconies and the like). Wind building codes and standards are eagerly awaiting the research outcomes from these particular research studies in order to generate relevant design provisions. Also, the achievement of the required progress on the associated students' theses depends to a great extent on upgrading the wind pressure measurement instrumentation which allows proceeding with the wind tunnel experimental research. It is necessary to point out that research students can easily get to grips with MPS 4264 and can stay current with research data collection and traceability.******The requested instrumentation will be purchased from Scanivalve Corporation at a total cost of $ 130,557.**
