In the Navier-Stokes equations, vortex tube stretching causes the cross-sectional area to shrink, the rotation speed to increase, and vorticity to grow, which is a key mechanism of the turbulent energy cascade.

UnverifiedThe core of the Navier-Stokes problem is that the nonlinear convection term concentrates energy into smaller scales and may cause blowup, while the viscous dissipation term tends to dissipate energy and maintain smoothness.77% similarVerifiedThe Navier-Stokes Equations describe the fundamental laws governing the motion of viscous fluids.71% similarUnverifiedA small Reynolds number means smooth, viscosity-dominated flow; a large Reynolds number means inertia dominates and the flow tends to become unstable and develop into turbulence.67% similarUnverified根据Rankine-Hugoniot关系，激波后的压力跃升与来流密度成正比，降低来流密度可减弱激波强度64% similar
