... has been used. Solver settings have been shown in Table 1 . The main challenge is to stimulate the nanoparticles dispersion in the methane fuel. In order to take the better simulation results, moving grid strategies have been applied. Refinement option has been used to resize the mesh and ensure...

...Peng Hui-Sheng; Yang Tian-Hang A comprehensive understanding of the effects of free radicals on the ignition properties of practical fuel is critical for the performance of hypersonic vehicles. In this study, the free radical effects of H, CH 3 , and C 2 H 5 on the ignition delay times of methane...

...Saeid Zare; Hao Wei Lo; Omid Askari Recently, methane has been investigated as a feasible fuel for propulsion systems. The higher boiling point and higher density of methane, compared with hydrogen, makes its storage tank lighter, cheaper, and smaller to launch. Methane is abundant in the outer...

...Omid Askari; Hameed Metghalchi; Siamak Kazemzadeh Hannani; Ali Moghaddas; Reza Ebrahimi; Hadis Hemmati Flame images of the partially premixed direct-injection combustion of methane at the equivalence ratio of 0.8, spark delay timing of 1 ms and different S.R. are shown in Fig. 10 . It can...
