1.   The ephemeral nature of fluid flow belies the rigid rules which govern its behaviour.

2.   Fluid flow turbulence, in contrast, is far too pervasive ever to have been regarded in this way.

3.   He developed a comprehensive mathematical model of fluid flow, electromagnetics, and heat transfer in metal processing.

4.   Like cholesterol, it gradually restricts fluid flow.

5.   Part of that debate concerned illegal Mexican immigrants and the push by Mexico to create a more fluid flow of migration back and forth across the border.

6.   Part of that debate concerned Mexicans and the push by Mexico to create a more fluid flow of migration across the border.

7.   She worked on projects like fluid flow to solve antisubmarine problems, hydrofoil designs and early rocketry.

8.   The programs simulate the fluid flow around hulls and appendages, like rudders, keels and ballast bulbs, or the movement of air around masts or sails.

9.   There are many different types of drops that can be used to relieve the pressure from ones that increase eye fluid flow to others that decrease eye fluid production.

10.   When a disruption occurs and the smooth layers of air curl up into tangled whorls, the fluid flow is said to be turbulent.
