摘　　要：在流场计算和油珠碰壁处理上进一步发展和完善了轨道扩散模型，编制了适用于具有多圈环形V型稳定器和多种喷油布置的加力燃烧室两态燃油浓度计算的通用程序。用于实际加力燃烧室的浓度场计算，可以给出加力燃烧室任意截面上液态、气态和总态燃油浓度分布，各区域内燃油浓度的平均值和周向平均燃油浓度沿径向的分布。The method of calculation of flow field and treatment of fuel droplets impinging on wall has been improved. A general cede used for calculating the fuel concentration in afterburner with V-shape flameholders and different arrangement of fuel ejectors has been developed' When applied to full scale afterburner, it can predict the accurate distribution of liquid, gas and both phase fuel on concentration on any cross section, as well as the average fuel concentration in every area.
