论文摘要
我们研究了嵌入式云的质量加载对风吹气泡演变的影响。我们使用1D流体动力学计算，并假设云足够多，以至于可以在连续的极限中对其进行处理，并且会发生快速混合，从而使注入的质量迅速与整体流动融合。嵌入云的破坏会增加气泡中的质量，从而增加其密度。质量加载会增加由于摩擦阻力而引起的未落下的恒星风的温度，并随着更多颗粒之间的可用热能的共享，可降低热震动气体的温度。质量加载可能会增加或减少体积平均气泡压力。质量装载的气泡较小，保留能量较少，径向动量较低，但是在所有检查的情况下，仍然能够在扫荡的气体上进行重要的$ PDV $工作。在后一个方面，与``淬灭''气泡的类似动量的类似动量的行为相比，气泡更类似于能量支持的气泡。
We investigate the effect of mass-loading from embedded clouds on the evolution of wind-blown bubbles. We use 1D hydrodynamical calculations and assume that the clouds are numerous enough that they can be treated in the continuous limit, and that rapid mixing occurs so that the injected mass quickly merges with the global flow. The destruction of embedded clouds adds mass into the bubble, increasing its density. Mass-loading increases the temperature of the unshocked stellar wind due to the frictional drag, and reduces the temperature of the hot shocked gas as the available thermal energy is shared between more particles. Mass-loading may increase or decrease the volume-averaged bubble pressure. Mass-loaded bubbles are smaller, have less retained energy and lower radial momentum, but in all cases examined are still able to do significant $PdV$ work on the swept-up gas. In this latter respect, the bubbles more closely resemble energy-conserving bubbles than the momentum-conserving-like behaviour of ``quenched'' bubbles.
