Measurements of Thermal Stratification in an HCCI Engine
Post, December 18, 2012 • Measurements of Thermal Stratification in an HCCI Engine As automotive and diesel engine companies strive to find more fuel efficient, environmentally friendly technologies, some have turned their attention to Homogenous Charge Compression Ignition (HCCI). HCCI engines use fuel mixed with a substantial amount of excess air or recirculated exhaust gas...
Multi-disciplinary Research at Work: Combustion Exascale Co-Design Center Established
Post, March 21, 2012 • Combustion research has never been timelier; in an era when resources are limited, energy costs are rising, and environmental concerns demand consideration, top researchers must find new ways to maximize efficiency while minimizing costs. Combustion accounts for roughly 85% of the total energy used in the U.S.--developing technologies to improve...
Multiphase Systems
Page • The interaction of gas phase molecules with other phases bridges two systems—condensed phase and gas phase—that are described by different paradigms of chemical physics. Our research in multiphase systems focuses on understanding how these regimes affect each other and the nature of the intermediary region between the phases. Two areas...
Near-Surface Imaging
Page • Figure 1 Gas-surface interfaces are present in many important chemical systems. From the valorization of methane at catalytically active surfaces, to the impinging of combustion processes on chemically inert interfaces, the complex heterogeneous chemistry and molecular energy transfer processes occurring in the gas phase very near to interfaces must be...
Negative Valve Overlap: A Key to Controlling Lean, Gasoline Auto-Ignition?
Post, October 21, 2013 • By Richard Steeper The drive for cleaner, more efficient engines has pushed research toward low-temperature gasoline combustion (LTGC) strategies that offer hope of achieving mandates for ultra-low engine-out emissions. Such strategies typically exploit auto-ignition to avoid the high-temperature flames associated with spark ignition. However, this approach makes LTGC control a...
New Conceptual Insights into Diesel Engine Fuel-Injection Processes
Post, March 12, 2014 • By Joe Oefelein By combining advanced theory and high-fidelity large eddy simulation, CRF researchers Rainer Dahms and Joe Oefelein have provided new conceptual insights that promise to improve the understanding and prediction of fuel-injection processes at high-pressure diesel engine conditions. Their results, which were corroborated by experiments performed by CRF...
New Diagnostic Capability Provides 3-D Measurements of Turbulent Flame Dynamics Using High-Repetition Rate Tomographic Particle Image Velocimetry
Post, July 24, 2014 • Capturing turbulence–flame interaction structure and studying time–history effects requires high-speed volumetric measurements performed at repetition rates sufficiently fast to resolve the relevant flow time scales. Advances in the CRF’s imaging diagnostic capabilities are overcoming these challenges to provide a more complete picture of the structure and dynamics of turbulence–flame interactions....

Miller and Stephen J. Klippenstein have developed a set of theoretical methods for predicting the rates of collisional energy transfer that govern pressure dependence.1 Enabled by both...
New Polarized-Depolarized Measurement Capability Extends Use of Raman/Rayleigh Methods to More Flame Types
Post, February 26, 2014 • By Robert Barlow Allowing single-shot measurements of all major species in nonsooting flames of simple fuels, such as H2 and CH4, spontaneous Raman scattering has been a key CRF laser diagnostic technique for fundamental turbulent-combustion studies. However, laser-induced fluorescence from soot precursors tends to interfere significantly with Raman scattering signals—limiting...
New Take on an Old Laser Diagnostic Opens Up Additional Avenues for Combustion Research

New work by CRF researchers chosen as a “HOT” paper in the journal Physical Chemistry Chemical Physics
Post, July 12, 2012 • The oxygen atom is a critical oxidizer of hydrocarbons in high temperature combustion. Combustion models need to predict the products of these reactions accurately. Unlike other oxidizers, when O atoms react with hydrocarbons it is difficult to predict the products because of the effects of electron spin. New research that...
