Title: Chemically-reacting Fluid Flow Simulations, with Applications to Engines
Date: Tuesday, May 26, 2009
Time:11:00AM - 12:00PM ET
Featured Presenter: John Abraham, Professor of Mechanical Engineering, Purdue University
A significant fraction of the energy utilized in power plants and transportation is generated by burning fuels. Improving the efficiency of the chemical conversion process that occurs during burning can yield an immediate positive impact on reducing climate-changing, greenhouse gas emissions and other toxic pollutant emissions affecting human health.
Achieving these efficiency improvements requires both an understanding of fuel chemistry fundamentals and of the interaction between fuel chemistry and fluid flow. Chemically-reacting fluid flow simulations help scientists increase their understanding of the physics and enable the design of more energy-efficient engine technologies.
In this webcast, John Abraham, Purdue University Researcher and Professor of Mechanical Engineering, will discuss his team’s investigations into:
- The effect of turbulence on non-premixed flames in diesel engines.
- Ignition in stratified mixtures in direct-injection spark-ignition and compression-ignition engines.
- Flame propagation in stratified mixtures in direct-injection hydrogen engines.
- Turbulence-ignition kernel interactions in lean-burn natural gas engines.
Professor Abraham will review Flow, Large-Eddy and Direct Simulation (FLEDS), the in-house developed code used to carry out the simulations. It has been run on up to 800 processors, and over 2 million combined processor hours have been logged for this research on the SiCortex system at Purdue over the past year.
