Abstract:
To study an evaporative flame-holder suitable for the ramjet combustor, the numerical simulation and analysis of two-phase combustion flow field for combustion characteristics and the fuel supply matching was carried out based on PDF combustion model. The influence of different main combustion zone / local fuel-feeding matching and fuel-feeding density distribution in different main combustion zone on the combustion performance were studied emphatically. An optimization fuel-feeding scheme for peak value and uniformity of gas temperature were obtained. The calculation result of the scheme is rational. It has an important significance for the optimization design for the fuel-feeding scheme of the evaporative flame-holder.
