流体动力学的隐喻光学计算
Metaphoric optical computing of fluid dynamics
摘要：
我们提出的理论和数值证据表明，自散焦的非线性光学传播可以用来计算欧拉流体动力学和可能的Navier-Stokes流体动力学。特别地，利用非线性薛定谔方程数值模拟了双涡和障碍物后卡门涡街这两种著名的粘性流体现象。
英文摘要：
We present theoretical and numerical evidence to show that self-defocusing nonlinear optical propagation can be used to compute Euler fluid dynamics and possibly Navier-Stokes fluid dynamics. In particular, the formation of twin vortices and the Kármán vortex street behind an obstacle, two well-known viscous fluid phenomena, is numerically demonstrated using the nonlinear Schrödinger equation.
