To avoid the complexities associated with the droplet/vapor transport and nonuniform evaporation processes, a fundamental investigation of liquid fuel combustion in idealized configurations is very useful. An experimental–computational investigation of prevaporized n-heptane nonpremixed and partially premixed flames established in a counterflow burner is described. There is a general agreement ...

Large-eddy simulations with a transported probability density function model coupled finite-rate chemistry is applied to study the ignition process of an n-heptane spray in constant volume chamber premixed methanol-air atmosphere under conditions relevant reactivity controlled compression (RCCI) engines. Three reacting cases initial equivalence ratio (?m) ranging from 0 0.3 are investigated at ...

In spinach chloroplasts which have been shaken with n-heptane, photophosphorylation coupled to the reduction of nicotinamide adenine dinucleotide phosphate is inhibited about 95% while the photoreduction of NADP+ (and ferricyanide) is stimulated as much as 50%. Photophosphorylation catalyzed by phenazine methosulfate, however, is inhibited only 50%. These data are interpreted to indicate that t...

This study analyzed factors that influence the ignition delay characteristics of n-heptane/methane-blended fuel. The effects chemical species, exhaust gas recirculation rate, compression ratio, cool/hot flames, and combustion chamber conditions (temperature, pressure, O2 concentration) were determined using CHEMKIN Pro. experiment for verification 550–1000 K at 15 bar with 50% H2/50% CH4 main r...

The auto-ignition of toluene and n-heptane as model fuels for Diesel fuel components have been studied in a highpressure shock tube under engine-relevant conditions. Toluene/air and n-heptane/air mixtures as well as toluene/nheptane/air (10/90% and 40/60% by volume) have been investigated over a wide temperature range (700 – 1200 K), = 1.0 and 0.5 and 40 bar behind reflected shock waves. A kine...
