论文摘要
我们为Bañados，Teitelboim，Zanelli（BTZ）黑洞提供了一个模拟模型，该模型基于流体动力学。我们从数值上求解了运动的完全非线性流体动力方程，并观察到该过程中模拟BTZ准模式的激发和衰减。我们认为在流体的稳态构型和较大的扰动中，这既有小的扰动。后者可以被视为形成类似物（声学）BTZ黑洞的一个例子。
We present an analog model for the Bañados, Teitelboim, Zanelli (BTZ) black hole based on a hydrodynamical flow. We numerically solve the fully nonlinear hydrodynamic equations of motion and observe the excitation and decay of the analog BTZ quasinormal modes in the process. We consider both a small perturbation in the steady state configuration of the fluid and a large perturbation; the latter could be regarded as an example of formation of the analog (acoustic) BTZ black hole.
