摘　　要：为满足小型热气机常温常压条件下燃烧的需要,在数值模拟的基础上设计了一种盘式旋流气体燃烧器,并试验研究了不同开孔方式、负荷条件和过量空气系数下燃烧室内的温度分布和火焰形状,结果表明:燃气孔为内孔,空气旋转流动,同时燃烧器外径减小到原来的2/5左右的情况下,燃气-空气混合均匀,燃烧稳定,火焰透明、脱壁且不直接灼烧加热器头部,高温区分布合适,满足热气机燃烧要求。To meet the requirement of a small-sized hot air engine for combustion under a normal temperature and pressure condition,designed was a disk type eddy flow gas burner on the basis of a numerical simulation. Experimentally studied were the temperature distribution and flame morphology in the combustor under the following conditions: various hole-opening modes,loads and excess air factors. The research results show that the gas holes are inner ones and the air assumes a rotation flow. Under the condition that...
