Investigation of Asymmetric Free and Confined Three-dimensional Turbulent Jets using Time-Resolved Tomographic Particle Image Velocimetry

提出了一种新的数值模拟和实验研究方案，用于研究自由射流和偏离固壁或自由表面的射流的混合和湍流特性。这些喷射器出现在许多工程应用中。这项研究的主要目标是提供对这些射流中湍流混合的科学了解，并创建一个高质量数据库的储存库，使研究界能够开发出可靠的湍流射流预测工具。短期目标是了解喷嘴几何形状的变化如何影响自由射流的湍流特性，以及评价射流与刚性壁面或自由表面的偏移距离对湍流输运现象的影响。在这个为期5年的周期中，将对16名HQP(5名博士、1名硕士和10名学士)进行培训，以进行新的实验和数值模拟，使他们能够对湍流射流有一个透彻的了解。他们将培养技能，为在学术界或对加拿大具有社会经济重要性的不同行业就业做好准备。

A novel numerical and experimental research program is proposed to investigate the mixing and turbulence characteristics of free jets, and jets that are offset from a solid wall or free surface. These jets occur in many engineering applications. The main goal of the research is to provide scientific understanding of turbulence mixing in these jets and create a repository of high-quality databases that will enable the research community to develop reliable predictive tools for turbulent jets. The short-term objectives, which will be achieved over the next 5 years, are to understand how changes in nozzle geometry affects turbulence characteristics of free jets, and to evaluate the effects of offset distance of a jet from a rigid wall or free surface on turbulent transport phenomena. Over this 5-year cycle, 16 HQP (5 PhD, 1 MSc and 10 BSc) will be trained to perform novel experiments and numerical simulations that will enable them to develop a thorough understanding of turbulent jets. They will develop skills that will prepare them for employment in academia or diverse industries of socio-economic importance to Canada.
