In the Ellis wormhole metrics, we study the characteristics of fluid dynamics and the properties of linear sound waves. By implying the energy–momentum equation and the continuity equation in the general relativistic manner, we examine the flow dynamics and solve the corresponding equations for a relatively simple case — radial flow. To study the linear sound waves, the equations governing the mentioned physical system are linearized and solved and interesting characteristic properties are found.

埃利斯虫洞中的流体动力学

在埃利斯虫洞度量中，我们研究了流体动力学的特征和线性声波的特性。通过以广义相对论的方式暗示能量-动量方程和连续性方程，我们检查了流动动力学并求解了相对简单的情况——径向流动的相应方程。为了研究线性声波，控制上述物理系统的方程被线性化和求解，并发现了有趣的特征特性。
