The engine was modified to include a single hole, side mounted injector for 35 MPa hydrogen direct injection into the combustion chamber. The eight-hole diesel injector remained in the original centrally mounted position, serving as a pilot flame ignition source. The results showed that reduced hydrogen energy share causes an increase in size and intensity of the diesel pilot acting to accelerate the initial combustion reaction, which is not only due to the increased diesel quantity but also the shift in diesel flame distribution. However, the combustion transitions into a near identical mixing-controlled combustion phase regardless of energy share. For hydrogen injection timing variations at fixed 90 % energy share, advanced injection was found to directly impact the hydrogen combustion mode altering the proportion of fuel injected prior to ignition of the diesel flame and the extent of mixing that has occurred. The longer residence time also increases the overlap of the two fuels prior to ignition resulting in a lengthened ignition delay due to dilution of the diesel pilot.

Yet they share a common mathematical formulation and numerical method that can be traced back to the first solid-burning model, developed for wood combustion during the 1940s. In this paper, we investigate the origins, formulation, and historical context of this model. Developed during the Second World War, it brought together a team of five scientists, Phyllis Nicolson, John Crank, Douglas Hartree, Clement Bamford, and David Malan, from the University of Manchester, the University of Cambridge, and the Special Operations Executive, a British espionage and sabotage organisation. Their task was to solve the governing equations and apply them to improve small incendiary devices for the war effort. The model consists of the heat diffusion equation with a source term representing an Arrhenius-type pyrolysis reaction. The stiffness of the resulting partial differential equation made it difficult to solve with the techniques of the time. This challenge led the team to develop the second-order accurate semi-implicit Crank–Nicolson scheme. This breakthrough not only transformed numerical methods but also laid the foundations for computational fluid dynamics, modern heat transfer modelling, and advances in combustion and fire science. Overall, we highlight the historical roots of the first solid-fuel burning model, which, though born of wartime combustion research, has had a profound and lasting influence on today’s models and numerical methods.</div></div>","PeriodicalId":100104,"journal":{"name":"Applications in Energy and Combustion Science","volume":"24 ","pages":"Article 100404"},"PeriodicalIF":5.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145416156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review highlights recent progress in understanding and optimizing APR, with particular attention to catalyst development, reaction mechanisms, and process design strategies that influence product selectivity. Model compounds such as methanol, ethanol, ethylene glycol, and glycerol serve as representative substrates to probe the complex network of dehydrogenation, C–C and C–O bond scission, water-gas shift (WGS), and methanation reactions. Advances in catalyst design, ranging from noble metals (e.g., Pt, Pd) paired with oxygen-vacancy-rich or hydroxylated/acidic/basic supports, to non-noble systems (e.g., Ni–Sn, Ni–Cu, N-doped carbons), are discussed in terms of their ability to tune the H<sub>2</sub>/CH<sub>4</sub> production. While certain catalysts promote reforming and WGS to favor hydrogen, others bias the route toward methanation, revealing the catalyst as a key variable for this reaction, in addition to the influence of conditions such as pressure and temperature.
