| Mon July 10th 2023 16:00 – 17:00 ZH286 | Seminar | Atmospheric Boundary Layer Turbulence: Influence on Heliostat Wind Loads Matthew Emes |
Details:Dr Matthew Emes is a Postdoctoral Research Fellow in the School of Electrical and Mechanical Engineering at the University of Adelaide in Adelaide, Australia. He received his PhD in Mechanical Engineering from the University of Adelaide in 2018 and has a background in experimental fluid mechanics, bluff body aerodynamics and atmospheric boundary layer turbulence. Since 2019, Dr Emes has co-led the Australian Solar Thermal Research Institute (ASTRI) heliostat wind load and aerodynamics project team and led the establishment of the Atmospheric Boundary Layer Research Facility (ABLRF) at the University of Adelaide. He and his team develop physical modelling techniques for wind tunnel simulation and field measurements of near-surface ABL turbulence parameters that influence wind load design of single heliostats, heliostat arrays and strategies for wind load reduction. His talk will provide an overview of the major outcomes from wind tunnel investigations on single heliostats and heliostat arrays at the University of Adelaide that highlight the importance of measuring and resolving the temporal and spatial variations of high-frequency ABL turbulence. Wind load prediction models developed from wind tunnel experiments are comparable with full-scale measurements on a single heliostat at the ABLRF, where the influences of atmospheric stability and turbulence length scales are observed. | ||
