A vortex in the atmosphere can churn with enough power to create a typhoon. But more subtle vortices form constantly in nature. Many of them are too small to be seen with the naked eye.
When simple, or "Newtonian" fluids (like water) flow very fast or along a curving path, swirling vortices develop. Their formation costs energy and increases "drag force," so that more energy is required to move a fluid in the desired direction. In large infrastructure like oil pipelines, the extra energy input required to pump the fluid comes at a significant financial cost. By adding small quantities of polymers to the oil, scientists can reduce the intensity of the vortices; the oil will then flow at the same speed but with a reduced pumping pressure, saving energy and money. While this phenomenon has been known about since the 1940s, many questions remain about exactly how the polymers work.
