This is the group of Dr. Georgios “George” Matheou in the Department of Mechanical Engineering. Our mission is to provide world-class education, engage and inform the general public, and solve significant problems using computational science to make a positive impact on society and the environment.
We are growing!
The Computational Fluid Dynamics group has immediate openings for graduate students and two Postdoctoral Research Associates: on large-eddy simulation of atmospheric convection, and computational fluid dynamics. We are also looking for dedicated and motivated undergraduate students to join our research team.
The Special Issue of the journal Atmosphere on “Turbulent Transport in Atmospheric Boundary Layers” is now open for submissions. Dr. Matheou is the Guest Editor for the Special Issue.
February 27: GABLS4 LES Model Intercomparison Paper
The paper documenting the GABLS4 LES Model Intercomparison study has been accepted in Boundary Layer Meteorology! Our LES model is one of ten models that contributed simulations to model a very stable Antarctic boundary layer. “GABLS4” is an interesting acronym: it is the Fourth GEWEX Atmospheric Boundary Layer Study, and GEWEX is the Global Energy and Water Exchanges project, which is as part of the World Climate Research Programme (WCRP). So, we contributed our LES to GABLS4, which is part of GEWEX under WCRP.
December 16: AGU Fall Meeting 2019
We participated in the AGU Fall Meeting with several presentations:
Monday, December 9
Residual Cross-Grid Flow Numerical Error in Large-Eddy Simulations of Cumulus-Topped Boundary Layers (A13N-3131)
Oumaima Lamaakel and Georgios Matheou
Infrared Instrument Radiance Modeling from Large Eddy Simulations to Access Sensitivity to Marine Planetary Boundary Layer Processes (A11T-2827)
Evan Fishbein, Bjorn Lambrigtsen, Matthew D. Lebsock, Georgios Matheou, Vivienne Payne, Mathias M. Schreier, Joao Teixeira, and Robert C Wilson
Inherent Properties of Clouds in the PBL Derived from Multi-angle Spectro-Polarimetric Imaging at the “Edge of Space:” New Capabilities of JPL’s AirMSPI Sensor on NASA’s Airborne ER-2 Platform (A11T-2828 )
Anthony B. Davis, Feng Xu, Gerard van Harten, David J. Diner, Aviad Levis, Yoav Y. Schechner, and Georgios Matheou
Wednesday, December 11
Boundary Layer Clouds and Climate: From LES to Simple Models (A32E-01)
Joao Teixeira, Georgios Matheou, Daniel Chung, and Peter Kalmus
Thursday, December 12
The spiderweb structure of stratocumulus clouds (A41Q-2873)
Georgios Matheou, Anthony B. Davis, and Joao Teixeira
December 6: An Art and Science Collaboration
Jonathan Goodrich and Liam McNeece two creative and talented students in Digital Media and Design created an informative and engaging animation to describe the dynamics of stratocumulus clouds. The animation was created in the Scientific Visualization class taught by Prof. Anna Lindemann. The animation seamlessly integrates Jonathan’s and Liam’s illustrations/animations with a movie from a high-resolution simulation of a stratocumulus cloud with our group’s large-eddy simulation model.
November 18: Weather and Art!
We visited Ms Govoni’s 7th Grade Art Class at Parish Hill High School and discussed clouds and weather. Inspired by our conversation, images and movies, students created marble art. Marble art has a striking resemblance to the Earths’s atmospheric motions: behaves like a two dimensional fluid with very little horizontal mixing. (more pictures coming soon!)
Our group participated in Research Connections 2019, a networking event at UConn intended to expose first and second year students to undergraduate research through engaging in meaningful interactions with faculty, staff, graduate students, and peers. Below, Oumaima Lamaakel, a graduate student in our group, is discussing her high resolution simulations of clouds and atmospheric dispersion. Many thanks to the Office of First Year Programs & Learning Communities (FYP&LC), the Office of Undergraduate Research for organizing the even!
Art and Science!
As part of the Fluid Dynamics I course, the Fluid Dynamics in Art and Nature exhibition (August 23 – October 13, 2019) at the Benton Museum of Art explores the intersection of art and science by bringing together works of art from the Benton Museum’s collection with computer simulations of natural phenomena. The exhibition aims to promote creativity, critical thinking, and self-learning. Fluid Dynamics in Art and Nature is curated by Dr. Matheou, and Dr. Amanda Douberley, Assistant Curator/Academic Liaison, Willian Benton Museum of Art.
Benton Museum Workshop: Thursday, October 10 at noon
As part of UConn’s Joule Fellows Program, we are hosting Ron Parlante, an Earth Science teacher at E. O. Smith High School, in our lab for six weeks. Ron has degrees in Meteorology and Education and he is passionate about convection and clouds. While running our high resolution computer model… he shot a movie of cumulus clouds. Joule Fellows is an NSF-funded Research Experience for Teachers (RET) program. Enjoy the view from our lab!
Also… Ron’s video about his experience and project:
Our latest paper on simulations of stratocumulus clouds is published in Monthly Weather Review.
Summer research experiences for teachers! We are participating in UConn’s Joule Fellows Program, an enrichment and personal development program for teachers. Two teachers will join us in our laboratory for five weeks in July and August. Together, we will work on discovering some of the secrets of cumulus clouds. The details of the two projects are on the program’s website along with the application details.
A discussion paper lead by our collaborators at Caltech is now available in Atmospheric Measurement Techniques. The paper demonstrates the use of high-resolution 2D plume imagery from airborne remote sensing retrievals to quantify methane point sources emissions. Significant improvements on the flux estimates without the need for direct wind speed measurements is demonstrated enabling the measurement of methane sources from space-based observations.
Dr. Matheou will present the Earth Science Seminar of the Science Visitor and Colloquium Program at the Jet Propulsion Laboratory on January 15.
Dr. Matheou was awarded the Center for Excellence in Teaching and Learning (CETL) Academic Mini Grant. The grant provides support for faculty innovation in teaching effectiveness and improved student learning outcomes. The project “Interactive wing design: Improving student engagement and learning in fluid dynamics” will be implemented in Fluid Dynamics I.
