Simulation of a Reacting Hydrogen Jet in Air Cross-Flow: Analysis of Inter-jet Spacing Impact in Gas Turbine Design
This study employs highly resolved simulations to evaluate the impact of injector spacing on a reacting hydrogen jet in a hot air cross-flow, revealing that intermediate-to-wide spacing (approximately eight diameters) offers the optimal design trade-off by balancing unburnt hydrogen throughput, wall heat transfer, and flow stability.
