Tea Seminar

Information transfer in energy-eddies of different sizes and why this is useful

Event Type: 
Tea Seminar
Date and Time: 
Friday, February 15, 2019 - 4:30pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Adrián Lozano-Durán
Abstract: 

Turbulent flows in the presence of bounding surfaces, as those occurring in oceanic and atmospheric currents, around vehicles, or inside pipes, may be apprehended as a collection of whirls or eddies.

A fast pressure-correction method for incompressible flows over curved walls

Event Type: 
Tea Seminar
Date and Time: 
Friday, January 25, 2019 - 4:30pm
Location: 
CTR Conference Room 103
Speaker(s): 
Visiting Associate Professor Antonino Ferrante
Abstract: 

We have developed a new pressure-correction method for simulating incompressible flows over curved walls. The methodology is applicable to DNS, LES and RANS.

Computational modeling of space re-entry aerothermodynamics and magnetized plasmas with COOLFluiD

Event Type: 
Tea Seminar
Date and Time: 
Friday, January 18, 2019 - 4:30pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Andrea Lani
Abstract: 

The COOLFluiD (Computational Object Oriented Libraries for Fluid Dynamics) project, which started in 2002 as a joint effort between the Von Karman Institute for Fluid Dynamics (VKI) and the Center for mathematical Plasma Astrophysics (CmPA) at the University of Leuven (KUL), has led to the develo

Input-output analysis of high-speed turbulent jet noise

Event Type: 
Tea Seminar
Date and Time: 
Friday, January 11, 2019 - 4:30pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Jinah Jeun
Abstract: 

In this talk we investigate amplifying behavior of small perturbations about Reynolds-averaged Navier-Stokes solutions of high-speed turbulent jets using input-output (I/O) analysis.  Inspired by control theory in electrical engineering, our method investigates how input forcing (jet turbulence)

Direct numerical simulation of turbulent flow and heat transfer in a spatially developing turbulent boundary layer laden with small solid particles

Event Type: 
Tea Seminar
Date and Time: 
Friday, October 19, 2018 - 4:30pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Dong Li
Abstract: 

Turbulent flows laden with particles are widely encountered in a great number of natural physical processes and in a host of industrial and environmental applications.

Color of Turbulence: Low-complexity stochastic dynamical modeling of turbulent flows

Event Type: 
Tea Seminar
Date and Time: 
Friday, October 5, 2018 - 4:30pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Armin Zare
Abstract: 

This talk describes how to account for second-order statistics of turbulent flows using low-complexity stochastic dynamical models based on the linearized Navier-Stokes (NS) equations.

Direct numerical simulation of grid-element turbulence and its effect on heat transfer

Event Type: 
Tea Seminar
Date and Time: 
Friday, May 18, 2018 - 4:30pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Immanuvel Paul
Abstract: 
Fractal-grid-generated turbulence has gained considerable attention in the past decade owing to its novel unique characteristics including the nonequilibrium energy cascade present in the near field.
