## Numerical Simulation of Flow in the Hartmann Resonance Tube and Flow in the Ultrasonic Gas Atomizer

• 摘要: 采用基于Roe解法的有限体积法，对Hartmann共振管中的气体流场进行了数值模拟，研究了当喷嘴轴线处存在针型激励器的情况下流场的振动情况，数值计算的结果与理论和相关的实验结果符合得较好．计算结果表明移除或引入激励器，将会使Hartmann共振管的共振模式发生转换．通过对超音速雾化喷嘴流场的数值模拟，研究了其中Hartmann共振腔和二级共振腔共同作用下的振动现象以及各物理参数对振动的影响，并对喷嘴中气流从亚音速向超音速的转变机理进行了研究．
