Welcome to the Flow Dynamics and Turbulence Laboratory

The Flow Dynamics and Turbulence (FDT) lab, led by Dr. Kianoosh Yousefi, is part of the Department of Mechanical Engineering at the University of Texas at Dallas. It is an interdisciplinary research group dedicated to understanding the nature of turbulence and examining turbulent flow processes in different natural, industrial, and engineering environments using experimental, numerical, and theoretical approaches. Particularly, our research agenda is focused on studying turbulent air-sea interaction processes, including surface waves and the accompanying generation of turbulence, spray, bubbles, airflow separation, and breaking waves. Another strand of our research is devoted to studying the turbulence structure in hurricane boundary-layer flows and examining the impacts of wind-wave interaction processes on offshore wind turbines and on-shore structures. In general, our research field is of interest to engineering, applied mathematics, and oceanography scholars. The physics learned from our work directly impacts our understanding of air-sea couplings and ocean waves, which is crucial for weather and climate forecasting and has significant societal benefits, impacting many aspects of human life.

Open Positions: We always seek exceptional graduate students and postdoctoral researchers to join our team and are open to collaborating on grant proposals. Graduate students and postdoctoral researchers interested in collaborating on fellowship and grant proposals are encouraged to explore the available opportunities with us. For details, please see the Join Us page.

Postdoc Positions in Sea Spray and Uncertainty Quantification

Open Postdoc Position in Sea-Spray Measurements: We are actively looking for a highly motivated postdoctoral researcher to join our research team to lead a synergistic research program based on laboratory measurements to evaluate the dynamics of spume droplets at high wind speeds. This will be accomplished by a combination of novel experiments based on high-speed shadow imaging to concurrently measure drop size distribution, production velocity, and deposition velocity and a digital-twin modeling framework to augment measurements with near-surface turbulence statistics and droplet-flow interactions. The resulting dataset enables the development of sea-state-dependent parameterizations of spray source function and spray-mediated fluxes (see the flyer).

Open Postdoc Position in UQ in Experimental Fluid Mechanics: We are actively looking for a postdoctoral researcher with a strong background in laboratory measurements to conduct fundamental research on uncertainty quantification in experimental fluid mechanics. This project is in direct collaboration with Dr. Edward White at UT Dallas and will focus on quantifying uncertainties in various fluid dynamic measurement techniques, including single point measurements, PIV flow visualizations, and laser Doppler anemometry, with applications in aerodynamics and air-sea interactions (see the flyer).
