In the AIRFlowS lab, we study a wide range of environmental, geophysical, and biological flow systems that are diverse in nature, scale, and physics. With a synergistic blend of numerical simulation, theory, experiment, and observation, we characterize momentum, energy, and pollutants in these systems. Our research is highly interdisciplinary and integrates the knowledge of environmental engineering, Earth and atmospheric science, fluid dynamics, computational science, and aerosol physics and chemistry. The AIRFlowS lab is led by Dr. Hosein Foroutan in the Department of Civil and Environmental Engineering at Virginia Tech.
