Online Seminar on Genesis of Flow Regimes in Canopy Flows by Prof. Alfredo Pinelli
Abstract
Surfaces of anchored filamentous layers exposed to fluid flows are commonly found in nature and in man-made environments. Few examples are: crop fields where the exchange of mass, heat, radiation and momentum between the canopy layer and the environmental surrounding regulates photosynthesis processes; ciliated walls in organs participating to a number of physiological processes like locomotion, digestion, circulation, respiration and reproduction; urban canopies where the interaction with the atmospheric boundary layer determines the local micro-climate. In this talk, after a review of the main parameters that govern the flow regime taking place inside and outside the canopy, and the numerical methods applied for carrying out resolved canopies simulations, we will describe in detail the flow structure in both straight and inclined canopies occurring in different regimes and the coupled interaction between the outer turbulent flow and the inner porous-like medium.
Finally, an overview of applications and the possibility of designing canopies and walls covered with textured surfaces, for specific technological purposes will be discussed.
Short Biography
Alfredo Pinelli is professor of fluid mechanics at City, University of London. He has received his PhD in applied mathematics from EPFL and holds a diploma course in fluid dynamics from VKI, where he has spent more than 3 years as an associate researcher.
He is a fellow of the Royal Aeronautical Society and Associate Dean for Research at the School of Science and Technology of City University. His main research interests are (but not limited to) numerical fluid mechanics, turbulent boundary layers, and flows over complex surfaces. He has authored more than 60 peer reviewed articles, including one of the most cited papers in the journal of fluid mechanics.
