The Role of the Large-Scale Structures in Turbulent Wall Jets by Joseph Hall
The development of the large-scale turbulent structures is experimentally investigated in both impinging jets and three-dimensional wall jets. An azimuthal decomposition of the fluctuating wall pressure in the impinging jet revealed the presence of large-scale ring structures; however, these ring structures did not appear to impact the wall concentrically. The development of three-dimensional wall jets exiting rectangular channels with aspect-ratios from 1 to 8 was investigated using the turbulent velocity and measurements of the fluctuating wall pressure. The development was found to be delayed by increasing the channel aspect-ratio, but the length-scales in the different jets could be collapsed by scaling the streamwise coordinate by the square root of the channel cross-sectional area and normalizing by the size of the channel. Pressure-velocity correlations indicate that the large-scale structures in these flows are strongly asymmetric.Joseph Hall has worked in nearly every aspect of modern technology, starting as a support technician and rising to web programmer, QA engineer, systems administrator, Linux instructor, and cloud engineer. He is currently employed with SaltStack as a senior cloud and integrations engineer. With his coworkers and SaltStack's partners, Joseph appreciates working with some of the brightest minds in the industry. He's also the author of Packt Publishing's Extending SaltStack.
