Tea Seminar

Development and Applications of PDE Solvers on Octree Adaptive Grids

Event Type: 
Tea Seminar
Date and Time: 
Friday, January 29, 2016 - 4:00am
Location: 
CTR Conference Room 103
Speaker(s): 
Frederic Gibou, Professor and MechE Graduate Program Director, University of California, Santa Barbara
Abstract: 

It is well recognized that computational science is the third pillar of discovery along with theory and experiments.

A LES study of interactions between wind turbine wakes and the atmospheric boundary layer

Event Type: 
Tea Seminar
Date and Time: 
Friday, January 8, 2016 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Shengbai Xie, Graduate Research Assistant, University of Delaware
Abstract: 

It is critical to understand how wind turbine wakes interact with the atmospheric boundary layer (ABL) in order to better estimate the wake loss in a wind farm.

Interaction between the atmospheric boundary layer and wind turbines

Event Type: 
Tea Seminar
Date and Time: 
Friday, November 6, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Mahdi Abkar, CTR Postdoctoral Fellow
Abstract: 

Wind turbines extract kinetic energy from the ambient flow in the turbulent atmospheric boundary layer (ABL). A profound understanding of the mutual interactions between ABL and wind turbines will indeed shed light on the path to the optimized wind farms.

Lagrangian subgrid modelling for the relative separation of tracers in turbulence

Event Type: 
Tea Seminar
Date and Time: 
Friday, October 2, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Federico Toschi, Team Leader PIV, German Aerospace Center
Abstract: 

Turbulence has an important influence on the transport of small particulate matter like dust in the atmosphere, fuel droplets in combustion chambers and small biological organisms in marine environments.

Shake-­The-­Box: A 4D-­PTV method for turbulence characterization at high particle densities

Event Type: 
Tea Seminar
Date and Time: 
Friday, September 18, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Andreas Schröder, Team Leader PIV, German Aerospace Center
Abstract: 

In order to increase the prediction capabilities of advanced numerical methods for turbulent (wall bounded) flows at relatively high Reynolds numbers, accurate experimental validation data-­sets including the full Reynolds stress tensor at high spatial resolution are urgently required.

Turbulent Flow over Bluff Bodies: From Sub-Critical to Super-Critical Flow Regimes

Event Type: 
Tea Seminar
Date and Time: 
Friday, September 11, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Oriol Lehmkuhl, Professor, Technical University of Catalonia, Spain
Abstract: 

This seminar will focus on the numerical simulation of the turbulent flow past bluff bodies which is of importance due to its presence in many engineering applications (flows past an airplane, submarine, automobile, in turbomachines, etc.).
