However, thermocapillary flows on Earth are very difficult to study because they are often masked by much stronger buoyancy-driven flows.

However, the analysis of compressible flows in the transonic regime has led to some developments which help reduce the increases in drag caused by compressibility effects, including the use of swept wings and the Whitcomb area rule.

However, the hazard of using butterfly needles lies in the fact that as the blood flows through the rubber tubing, it cools significantly, thereby clotting faster.
