声波之间的对应关系,在一个德拉瓦尔推进喷嘴,和准正规模式发出的膜世界黑洞变形的5D散装外尔流体在这里探索和仔细检查。在实验室中的de拉瓦尔喷嘴的声波图案的分析,在这里示出,提供有关的数据的5D散装外尔流体和其上的膜投影,包括由最小的几何变形紧凑的恒星分布在膜上。在几何变形过程中,证明了de拉瓦尔喷管中气体流场的声扰动与黑洞解经Weyl流体变形后的准正规模相一致.因此,在一个唯象的Eötvös-Friedmann流体膜世界模型中,导出了de拉瓦尔喷管的实际形状,并研究了其后果。
The correspondence between sound waves, in a de Laval propelling nozzle, and quasinormal modes emitted by brane-world black holes deformed by a 5D bulk Weyl fluid are here explored and scrutinized. The analysis of sound waves patterns in a de Laval nozzle in the laboratory, reciprocally, is here shown to provide relevant data about the 5D bulk Weyl fluid and its on-brane projection, comprised by the minimal geometrically deformed compact stellar distribution on the brane. Acoustic perturbations of the gas fluid flow in the de Laval nozzle are proved to coincide with the quasinormal modes of black holes solutions deformed by the 5D Weyl fluid, in the geometric deformation procedure. Hence, in a phenomenological Eötvös–Friedmann fluid brane-world model, the realistic shape of a de Laval nozzle is derived and its consequences studied.
