大的灰尘分数可以阻止声波的传播

Large dust fractions can prevent the propagation of soundwaves

Timothée David--Cléris, Guillaume Laibe

摘要:

尘埃在几个天体物理过程中起着核心作用。因此,需要粉尘/气体的数值解,和分析问题,以基准。在开创性的dustywave问题,我们发现了一个政权,声波不能通过传播的混合物上一个大的临界粉尘分数。我们分析了这个政权,使其用于测试精度的数值求解器在大尘埃分数。

英文摘要:

Dust plays a central role in several astrophysical processes. Hence the need of dust/gas numerical solutions, and analytical problems to benchmark them. In the seminal dustywave problem, we discover a regime where sound waves can not propagate through the mixture above a large critical dust fraction. We characterise this regime analytically, making it of use for testing accuracy of numerical solvers at large dust fractions.
