论文摘要
可以通过汇合HEUN函数来分析描述排水涡流中的扰动。在理想流体中重力模型的背景下,我们使用汇合的HEUN函数在分析上研究了排水浴缸中波的吸收长度,即旋转的黑洞类似物。我们将分析结果与相应的数值结果进行比较,并获得了极好的一致性。
Perturbations in a draining vortex can be described analytically in terms of confluent Heun functions. In the context of analogue models of gravity in ideal fluids, we investigate analytically the absorption length of waves in a draining bathtub, a rotating black hole analogue, using confluent Heun functions. We compare our analytical results with the corresponding numerical ones, obtaining excellent agreement.
