Recent studies showed that current H-2/CO kinetic models failed to match the measured laminar flame speeds of H-2/O-2/CO2 mixtures at high pressures. To explore the source of discrepancy, we performed uncertainty analysis using the Data Collaboration method, and obtained dataset inconsistency if these measured values were included. We then conducted experiments at similar conditions and found that our new measured values are consistent with other data in the dataset. Our uncertainty analyses suggest two approaches to improve the model prediction performance: by reducing the uncertainties of model parameters directly, and by designing and conducting experiments that can effectively constrain the model predictions.
