Abstract
This paper details an experimental investigation into flame propagation of a stoichiometric hydrogen mixture within a fixed 40 cm3 volume channel, utilizing ANSYS Fluent for simulation. The geometry was delineated as a 200x20 mm plane, with ignition positioned at the center. Certain input parameters were determined using MATLAB's Cantera. The study explored different configurations of ANSYS Fluent's channel combustion models, specifically examining both laminar and turbulent scenarios. Overpressure within the chamber was gauged at points 50 mm from the channel's center to assess the impact of the relaxation factor on these measurements. These models underwent comparative analysis with actual experimental results, focusing on the highest achieved pressures and the flame's shape at 1.9 ms, 2.9 ms, and 4.8 ms post-ignition. The findings underscore the complexity of modelling hydrogen mixture combustion in enclosed channels, highlighting the necessity for a specialized approach. Standard modules struggled to accurately replicate pressure variations over time, leading to significant discrepancies between the resulting models.
