DNS AND LES OF STABILIZATION AND INSTABILITIES IN ROCKET ENGINES

Event Type: 
CTR Tea
Date and Time: 
Friday, July 10, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Thierry Poinsot, Research Director, CNRS, Toulouse and Head of CFD group CERFACS
Abstract: 

Liquid fuel rocket engines using H2/O2 combustion are again a major research theme in Europe especially for the future Ariane 6 rocket. This talk will present recent progress in two critical mechanisms controlling combustion in cryogenic H2/O2 rocket engines.

Phase-­field modeling of multiphase flows using the lattice Boltzmann method with adaptive mesh refinement

Event Type: 
CTR Tea
Date and Time: 
Friday, June 5, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Abbas Fakhari, CTR Postdoctoral Fellowship Candidate, Mechanical Engineering, City College of New York
Abstract: 

Numerical modeling of multiphase flows at high Reynolds numbers is a challenging task. Traditional methods based on sharp-­interface models might encounter numerical difficulty in handling rapid topological changes such as breakup and coalescence.

Identifying coherent structures in fluid flow

Event Type: 
CTR Tea
Date and Time: 
Friday, May 29, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Prof. Gary Froyland, School of Mathematics and Statistics, University of South Wales, Sydney, Australia
Abstract: 

The future behavior and transport mechanisms of complicated (chaotic or "turbulent") fluid flow is hard to predict.  However, in many situations there are regions of predictability embedded in the flow that exhibit approximately regular behavior.

Particulate flow across multi-scales: numerical strategies for momentum, heat and mass transfer

Event Type: 
CTR Tea
Date and Time: 
Friday, April 24, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Anthony Wachs, Fluid Mechanics Department,IFP Energies nouvelles, Solaize, France
Abstract: 

Particulate flows are ubiquitous in environmental, geophysical and engineering processes. The intricate dynamics of these two-phase flows is governed by the momentum transfer between the continuous fluid phase and the dispersed particulate phase.

Gas-solid flow analysis using particle-resolved direct numerical simulation: mechanism, quantification and modeling

Event Type:

Friday, April 17, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Mohammad Mehrabadi, Mechanical Engineering, Iowa State University, Ames, IA
Abstract: 

Gas-solid flows are encountered in many industrial processes such as pneumatic conveying, fluid catalytic cracking, CO2 capturing and fast pyrolysis process.

Numerical simulation of multiphase immiscible flow on unstructured meshes

Event Type: 
CTR Tea
Date and Time: 
Friday, February 20, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Dr. Lluis Jofre-Cruanyes, Postdoctoral Fellow, Center for Turbulence Research
Abstract: 

The present talk tries to summarize the work performed by Lluis Jofre-Cruanyes during his PhD.The research aims at developing a basis for the numerical simulation of multiphase flows of immiscible fluids.

Rethinking tsunami preparedness - What is the role of vegetation?

Event Type: 
CTR Tea
Date and Time: 
Friday, February 6, 2015 - 4:00pm
Location: 
CTR Conference Room 103
Speaker(s): 
Professor Jenny Suckale, Geophysics Department, Stanford University
Abstract: 

The role of coastal forests in the mitigation of tsunami disasters has become a hotly debated topic in the aftermath of the devastating tsunami in the Indian Ocean in 2004 and Japan in 2011.
