Hydrogen is an interesting fuel for internal combustion engines. It is a versatile fuel that enables high efficiencies and low emissions of oxides of nitrogen (NO x ), throughout the load range.Computer simulations of hydrogen-fuelled spark ignition engines would facilitate the development of these engines. These necessitate the calculation of the turbulent combustion of hydrogen to track the flame propagation throughout the combustion chamber and resolve in-cylinder pressure and temperature. In order to do this, the laminar burning velocity of the in-cylinder mixture at the instantaneous pressure and temperature is needed. However, there is a scarcity of data in the literature, particularly at engine conditions. This is further complicated by the occurrence of flame instabilities at engine-like pressures, which compromises some of the existing data.This paper discusses the available experimental data and correlations for the laminar burning velocity of hydrogen mixtures, and their deficiencies. One-dimensional chemical kinetic calculations of the laminar burning velocity of mixtures of hydrogen, air and residuals, at engine-like pressures and temperatures are then reported. A correlation is derived for use in hydrogen engine codes and is compared to other correlations presented previously.2

“…Independent of pressure and equivalence ratio the principal behaviour of the investigated reaction mechanisms is the same for all six test cases. The skeletal Jachimowski scheme is the fastest one, followed by the Vajda et [26]. From Figure 1 it can be concluded that with the exception of the one-step kinetic model, the skeletal Jachimowski, and the GRI3.0 mechanism, the four remaining schemes are relatively close together and, at least at higher temperatures, are within the accuracy of the available experimental data.…”

“…The wide pressure ranges of both mechanisms require the consideration of pressure dependencies for some three body reactions. The GRI3.0 mechanism has been developed for methane combustion, but is also validated for the stoichiometric combustion of hydrogen/air mixtures at pressures of 1 and 2 bar [26] and has been used for supersonic combustion [27].…”

SUMMARYThe simulation of supersonic combustion requires finite-rate chemistry because chemical and fluid mechanical time scales may be of the same order of magnitude. The size of the chosen reaction mechanism (number of species and reactions involved) has a strong influence on the computational time and thus should be chosen carefully. This paper investigates several hydrogen/air reaction mechanisms frequently used in supersonic combustion. It is shown that at low flight Mach numbers of a supersonic combustion ramjet (scramjet), some kinetic schemes can cause highly erroneous results. Moreover, extremely fine computational grids are required in the lift-off region of supersonic flames to obtain grid-independent solutions. The fully turbulent Mach 2 combustion experiment of Cheng et al. (Comb. Flame 1994; 99: 157-173) is chosen to investigate the influences of different reaction mechanisms, grid spacing, and inflow conditions (contaminations caused by precombustion). A detailed analysis of the experiment will be given and errors of previous simulations are identified. Thus, the paper provides important information for an accurate simulation of the Cheng et al. experiment. The importance of this experiment results from the fact that it is the only supersonic combustion test case where temperature and species fluctuations have been measured simultaneously. Such data are needed for the validation of probability density function methods.

Predictive modeling of chemical reaction systems is facilitated through development of an automated data-centric infrastructure, Process Informatics Model (PrIMe). Modeling and analysis tools were built to bridge the PrIMe Data infrastructure with DataCollaboration, a framework designed to make inferences from experimental observations in the context of an underlying model. The developed tools were integrated with the PrIMe Workflow Application, allowing users to create and run drag-and-drop applications on the fly. Organizing the data, linking the data to scientific methods, and automating the analysis offer new venues of scientific inquiry, such as evaluating the consistency of heterogeneous data records, making uncertainty-quantified predictions, quantifying the contribution of newly obtained or even hypothetical data to the question of interest, or testing similar "what-if" scenarios. The developed system is demonstrated for the chemical kinetics of hydrogen combustion. C
