“…These interactions lead to increased heat loss from a flame, resulting in a local gas temperature reduction of 200 K or more. This TRI cooling effect is even more pronounced in high-pressure combustors, which typically exhibit greater optical thickness, as highlighted in [66,67].…”

The aim of this article is to review hydrogen combustion applications within the energy transition framework. Hydrogen blends are also included, from the well-known hydrogen enriched natural gas (HENG) to the hydrogen and ammonia blends whose chemical kinetics is still not clearly defined. Hydrogen and hydrogen blends combustion characteristics will be firstly summarized in terms of standard properties like the laminar flame speed and the adiabatic flame temperature, but also evidencing the critical role of hydrogen preferential diffusion in burning rate enhancement and the drastic reduction in radiative emission with respect to natural gas flames. Then, combustion applications in both thermo-electric power generation (based on internal combustion engines, i.e., gas turbines and piston engines) and hard-to-abate industry (requiring high-temperature kilns and furnaces) sectors will be considered, highlighting the main issues due to hydrogen addition related to safety, pollutant emissions, and potentially negative effects on industrial products (e.g., glass, cement and ceramic).

“…The RTE models, P 1 , SP 3 and SP 5 require 0.0312s, 0.125s and 0.172s, respectively, for each quadrature on average. Because SP 3 and SP 5 involve extra iterations between 2 and 3 equations respectively, their time costs are more than 2 and 3 times the P 1 cost, respectively. The present calculations are based on a mesh of 3325 cells and an 8 point quadrature scheme for the cumulative k-distribution.…”

New spectral radiation models for combustion gases at elevated pressures, for both conventional and stochastic solution methods, were developed. Several Radiative Transfer Equation (RTE) solution methods were newly designed (development of cell-based as well as stochastic particle-based, line-by-line accurate, photon Monte Carlo methods, and formulation and coding of higher-order, 3D spherical harmonics as well as simplified PN schemes). To allow simulation of high-pressure laminar flames required modification of the open source flow code used (OpenFOAM) to include differential diffusion and cell-based stochastic RTE solvers. The models were validated by simulation of laminar high-pressure hydrogen-air flames, as well as turbulent methane-air jet flames.
