Draft:Ugo Piomelli
| Submission declined on 18 June 2025 by Rambley (talk). This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia.

Ugo Piomelli is a mechanical engineer known for his contributions to the field of computational fluid dynamics, particularly in turbulence modeling and large-eddy simulation. He is currently a professor at Queen's University at Kingston. He is also Editor-in-Chief of the Journal of Turbulence.
Career and research
[edit]Piomelli was born in Naples, Italy. He earned a Laurea in Ingegneria Aeronautica from the University of Naples Federico II in 1979. He completed his Master’s degree at the University of Notre Dame in 1983, focusing on the numerical analysis of solid blocking effects for two-dimensional flow past an airfoil in a wind tunnel.
He then pursued a Ph.D. under the supervision of Parviz Moin and Joel Ferziger at Stanford University, with much of his early research conducted at NASA Ames Research Center. His doctoral work focused on subgrid-scale models for large-eddy simulations.
In 1987, Piomelli began his academic career as a faculty member in the Department of Mechanical Engineering at the University of Maryland, College Park. Over the next 21 years, he advanced through the academic ranks and served as Associate Chair and Director of Graduate Studies from 2002 to 2007.
In 2008, he joined the Department of Mechanical and Materials Engineering at Queen’s University in Kingston, Ontario as the Tier 1 Canada Research Chair in Turbulence Simulation and Modelling.
Impact
[edit]Ugo Piomelli has made significant contributions to the field of computational fluid dynamics, particularly in the development and application of large-eddy simulation (LES) techniques for turbulent flows. His work has advanced the understanding and modeling of turbulence, leading to more accurate and efficient computational methods used in various engineering applications.
Among Piomelli's most influential contributions is his co-authorship of the 1991 paper introducing the dynamic subgrid-scale eddy viscosity model for LES.[1] This model improves upon the classical Smagorinsky model by allowing the subgrid-scale viscosity to adapt dynamically to the local flow conditions, resulting in a more accurate representation of energy transfer in turbulent flows. The dynamic model has since become one of the most widely adopted approaches in LES and has significantly enhanced the predictive power of simulations in both academic and industrial settings. The original paper[1] has been cited over 10,000 times.
Piomelli further demonstrated the robustness and versatility of this model through its application to various flow configurations, including rough-wall boundary-layer flows, flows with separation and reattachment, and vortex-dominated flows. His work paved the way for the widespread use of LES in practical engineering problems such as aerospace design, wind energy, and geophysical flow modeling. It has also helped understand physical phenomena that govern complex turbulent flows.
Beyond his research achievements, Piomelli has been instrumental in mentoring the next generation of researchers and engineers in fluid mechanics. Many of his former students and collaborators have gone on to distinguished careers in academia, research laboratories, and industry.
Awards and honors
