Accelerating reactive-flow simulations using vectorized chemistry integration
Nicholas J. Curtis, Kyle E. Niemeyer, Chih-Jen Sung
The high cost of chemistry integration is a significant computational bottleneck for realistic reactive-flow simulations using operator splitting. Here we present a methodology to…
Using SIMD and SIMT vectorization to evaluate sparse chemical kinetic Jacobian matrices and thermochemical source terms
Nicholas J. Curtis, Kyle E. Niemeyer, Chih-Jen Sung
Accurately predicting key combustion phenomena in reactive-flow simulations, e.g., lean blow-out, extinction/ignition limits and pollutant formation, necessitates the use of detail…
An automated target species selection method for dynamic adaptive chemistry simulations
Nicholas Curtis, Kyle Niemeyer, Chih-Jen Sung
The relative importance index (RII) method for determining appropriate target species for dynamic adaptive chemistry (DAC) simulations using the DRGEP method is developed. The accu…
On the uncertainty of temperature estimation in a rapid compression machine
Bryan W. Weber, Chih-Jen Sung, Michael W. Renfro
Rapid compression machines (RCMs) have been widely used in the combustion literature to study the low-to-intermediate temperature ignition of many fuels. In a typical RCM, the pres…
Comparative Autoignition Trends in the Butanol Isomers at Elevated Pressure
Bryan W. Weber, Chih-Jen Sung
Autoignition experiments of stoichiometric mixtures of s-, t-, and i-butanol in air have been performed using a heated rapid compression machine (RCM). At compressed pressures of 1…
Reduced chemistry for butanol isomers at engine-relevant conditions
Xin Hui, Kyle E. Niemeyer, Kyle B. Brady +1
Butanol has received significant research attention as a second-generation biofuel in the past few years. In the present study, skeletal mechanisms for four butanol isomers were ge…
