dc.description.abstract |
The Engine Combustion Network (ECN) is a worldwide group of institutions using combustion vessels
and/or performing computational fluid dynamics (CFD) simulation, whose aim is to advance the state of
spray and combustion knowledge at engine-relevant conditions. A key activity is the use of spray chamber
facilities that operate at high-temperature, high-pressure conditions typical of diesel combustion, which are
operated at specific target conditions in order to leverage research capabilities and advanced diagnostics of
all ECN participants. The first target condition, called ¿Spray A,¿ has been defined with detailed ambient
(900 K, 60 bar, 22.8 kg/m3, 15% oxygen) and injector (common rail, 1500 bar, KS1.5/86 nozzle, 0.090-mm
orifice diameter, n-dodecane, 363 K) conditions. Establishing and improving these experimental boundary
conditions in unique facilities throughout the world represents a major step forward in the establishment of
high-quality, quantitative data sets for engine spray combustion. This paper is a review of the methodology
to characterize and control the ambient and fuel-injector boundary conditions (e.g., temperature, pressure,
composition) as offered by six different participating institutions of the ECN, each targeting the Spray A
conditions and quantifying experimental uncertainty. Constant-pressure flow (CPF) and constant-volume
preburn (CVP) chambers with various ambient gas composition are compared for the first time. Experimental
diagnostics include the use of fast-response, radiation-corrected thermocouples for spatially resolved gas and
fuel-injector temperature, laser-induced phosphorescence for surface temperature, and high-speed transducers
for pressure. With guidance about the uncertainty and variation that exists between facilities, simplified
models are then employed to understand how these boundary condition variations may affect aspects of spray
combustion. Ambient gas and fuel temperature effects on liquid- and vapor-phase penetration are examined
with established one-dimensional models. Chemical kinetics modeling in single- or multi-zone reactors is used
to predict the influence of different preburn environments on the major and minor species present in the ambient
gas at the start of injection, and their subsequent effect on spray ignition. This review article provides
recognition of the challenge in creating well-controlled high-temperature, high-pressure environments, and
identifies which boundary condition variations are expected to have the highest impact on spray combustion. |
