This study presents a thorough evaluation of the simultaneous planar laser-induced fluorescence (PLIF) on hydroxyl (OH) radicals and nitric oxide (NO), for characterizing hydrogen detonation fronts. The combines experimental numerical results to evaluate benefits drawbacks different visualization strategies, namely OH-PLIF alone, NO-PLIF + shock det. (comparable schlieren), combined OH- NO-PLIF. Main findings are: (i) For first time, single-shot visualizations are demonstrated waves three...
This study evaluates the performance of two-dimensional (2D) detonation simulations against recent experimental measurements for a stoichiometric hydrogen–air mixture at 25 kPa. The validation parameters rely on average cell size (λ), variability (2σ/λ), and dynamics both relative speed (D/DCJ) local induction zone length (Δi) along cycle. We select Mével 2017’s San Diego’s chemical models 2D simulations, after evaluating 13 with Zeldovich–von Neumann–Döring (ZND) simulations. From this...
An OpenFOAM® based hybrid-central solver called reactingPimpleCentralFoam is validated to compute hydrogen-based detonations. This a pressure-based semi-implicit compressible flow on central-upwind schemes of Kurganov and Tadmor. possesses the features standard solvers namely, rhoCentralFoam, reactingFoam pimpleFoam. The utilizes & Tadmor for flux splitting solve high-speed regimes with/without hydrodynamic discontinuity. In this work, we present validation results that were obtained...
Liquid phase stability is a major concern in the transportation and energy field where fuels, lubricants, additives have to be stable from their production site application (engine, combustors). Although alkanes are constituents of commercial fuels well-documented solvents, respective reactivities selectivities autoxidation poorly understood. This experimental modeling study aims at (i) enhancing current knowledge on alkane (ii) reviewing correcting previously established structure...
The control of deposit precursors formation resulting from the oxidative degradation alternative fuels relies strongly on understanding underlying chemical pathways. Although C8–C16 n-alkanes are major constituents commercial and well-documented solvents, their respective reactivities selectivities in autoxidation poorly understood. This study experimentally investigates influence chain length, temperature (393–433 K), purity, blending kinetics under concentrated oxygen conditions, using...
The primary objective of this study is to measure the laminar burning velocity perfectly premixed hydrogen-air, methane-air, ethane-air, ethylene-air, and propane-air flames, at nearcryogenic temperatures atmospheric pressure. Initial fuel-air mixture as low 160 K were investigated. experimental methodology was validated by comparing results obtained with those from previous studies available in literature numerical simulations using four different chemical mechanisms. First, for all fuels,...
This study investigates the effect of nitric oxide (NO) sensitization on stoichiometric 2H2-O2-3.76Ar and 2H2-O2-3.76N2 detonations at T0 = 294K P0 20 kPa initial conditions. Experimentally, both mixtures are doped with three levels NO seeding (0, 2000, 13000 ppm) addition is evaluated cell width based soot foil measurements in a rectangular channel. Three models from literature validated these new experimental by employing Ng method. The following conclusions obtained: experimentally, (i)...
