Estudio numérico del efecto de la presión en el proceso de mezcla metano-oxígeno en un arreglo de chorros 4-Lug Bolt

Numerical results of methane-oxygen mixing process in a contained 4-Lug-Bolt jets array system under the influence of pressure variation are presented. The analysis was divided in two stages, low and high pressure, under the flammability limits criteria. At low pressures the density was modeled with the ideal-gas equation and for high pressures with the Redlich-Kwong equation. The predictions show that the gas mixture is highly influenced by recirculation between oxygen and methane jets, as well as a dragging effect of oxygen over the methane jet. Moreover, the pressure has no influence on the lower flammability limit, whereas it does affect the upper flammability limit. Despite these effects on flammability limits, the pressure shows no significant effect on the mixing of methane-oxygen by diffusion.
