Abstract:
A series of combustion experiments were carried out using a fuel-rich GOX/kerosene gas generator,at mixture ratios from 0.25 to 0.50 and chamber pressures from 1.0 to 4.0 MPa. The effects of mixture ratio and chamber pressure on soot formation and deposition characteristics were obtained. The results showed that the state of chemical equilibrium was not attained in the combustion process. When mixture ratio is smaller than 0.4,soot deposition is not significant and increases with the increase of mixture ratio slightly; when mixture ratio is larger than 0.4,soot deposition increases remarkably. At chamber pressure from 1.0 to 4.0 MPa,soot formation is found to be strongly dependent on chamber pressure. There is a critical pressure for soot formation which is between 1.0～2.0 MPa. If chamber pressure is smaller than the critical pressure,there is no soot formation in the combustion.
