... of Silicon Carbide (SiC) foam and ceramic. The experiment was carried out on PRB for three different raw biogas mixtures at the firing rate of 200–400 kW/m 2 and stable combustion was observed for the equivalence ratio range of 0.75–0.96. The raw biogas mixtures of higher CO 2 percentage reduce the surface...

Amell This work evaluated the performance of a combustion chamber operating with a self-recuperative burner at various atmospheric pressures by means of computational fluid dynamics (CFD) simulation. The aim was to determine the effect of atmospheric...

.... In recent years, with great progress in common rail diesel injection technology, m pilot can be adjusted accurately by the electronic control system, which is an advantage for operation with the diesel–LNG dual-fuel. In order to optimize m pilot of the diesel–LNG dual-fuel engine, the combustion...

.... Experiments are conducted for various injection timings (9 deg, 12 deg, 15 deg, and 18 deg BTDC) and for different exhaust gas recirculation (EGR) rates (0%, 10%, 15%, and 20%) at 100 MPa injection pressure. Combustion, performance, and tail pipe emissions of common rail direct injection (CRDI) engine...

... flames presented better combustion performances when compared to low AR jet flames. The good combustion performance of the high AR jet flames was due to enhanced entrainment and mixing, which were induced by flame lifting. However, at low Re c and high co-flow, the low AR jet flames exhibited desirable...

... is observed for fuel blends PB20 + 50Fe and D + 50Fe when compared to D. This may be due to the higher surface energy of iron nanoparticles, which improves the mixing characteristics and assists rapid combustion. Further, for the blend PB20, slightly lower peak pressure is observed. Fig. 7 Variation...
