Accurate mapping of the wind can enable more efficient renewable energy technologies as well as more accurate monitoring and modeling of weather and climate. Current ubiquitous wind sensors provide pointwise records but scaling them to full field requires installation and maintenance of a large number of sensors, which can be cost prohibitive. Therefore, I will demonstrate an affordable alternative in which quantitative estimates of wind speed and direction are inferred based on visual observations of associated flow-structure interactions such as swaying trees and flapping flags, named visual anemometry (VA). To explore generalizability of VA, i.e., the procedure that does not require calibration measurements or a priori collection of training data, I conducted a laboratory study of VA in an open circuit wind tunnel using eight species of vegetation and modeled the relationship between the vegetation displacement fields and wind velocity.
Bio:
Dr. Roni Goldshmid is a postdoctoral scholar in the Graduate Aerospace Laboratories at the California Institute of Technology. Roni received her B.S. at the University of California, Berkeley, and her M.S. and Ph.D. in the department of Civil and Environmental Engineering at the Technion – Israel Institute of Technology. Roni was named a rising star in mechanical engineering by Stanford University (2022), has authored two successful grants (NSF 2019 and ISF 2018) and has received the Grinshpen prize for excellent research in environmental engineering and air quality (2016). Her research interests and expertise include experimental fluid dynamics, where she focuses on fundamental and applied problems such as fluid-structure interactions, boundary layer flows, and interpretation of imperfect empirical data.
