TMOF is a branched isomer of oxymethylene ether-2 (OME2) that, due to its high oxygen content and lack of direct carbon-carbon bonds, considerably reduces the formation of soot particles. To meet the challenges of a more flexible and sustainable power generation, a detailed understanding of its combustion properties is essential for its safe and efficient utilization, neat or in blends. In this work, two fundamental combustion properties of TMOF were studied: (i) Auto-ignition of TMOF/synthetic air mixtures (φ = 1.0; diluted 1:5 with N2) using the shock tube method at pressures of 1, 4, and 16 bar, and (ii) Laminar burning velocities of TMOF/air mixtures using the cone angle method at ambient and elevated pressures of 3 and 6 bar. Furthermore, the impact of TMOF addition to a gasoline surrogate (PRF90) on ignition delay times was studied using the shock tube method at φ = 1.0, 1:5 dilution with N2, T = 900-2000}, language = {en} } @misc{NgũgĩRichterBraunUnkhoffetal., author = {Ngũgĩ, John Mbũrũ and Richter, Sandra and Braun-Unkhoff, Marina and Naumann, Clemens and Riedel, Uwe}, title = {A study on fundamental combustion properties of oxymethylene ether-1, the primary reference fuel 90, and their blend: experiments and modeling}, series = {Combustion and Flame}, volume = {243}, journal = {Combustion and Flame}, publisher = {Elsevier BV}, issn = {0010-2180}, doi = {10.1016/j.combustflame.2022.111996}, pages = {14}, language = {en} }
