I have been invited to give a talk on fluid dynamics at Queens’ Mathematical Society this term. Details are yet to be decided, but the talk will be an introduction to fluids and a focus on boundary layers, including the mathematical notion of a singular limit.
While writing the talk, I thought it might be nice to have a little fun with it.
The flow of a | fluid is | governèd
By the interact-si | -on of | four main | forces:
Viscosity * gravity * inert-si- | -a and | pressure.
Depending on the context | one may | dominate an- | -other.
In fast flows | or large | lengthscales
Inert-si- | -a is | domin- | -ant
These include many im- | -portant | contexts
Such as household plumbing * oil pipelines * submar- | -ines : and the | upper | atmosphere.
Unfortunately * the | limit of | Reynolds number
Going to infinity | is a | singular | limit.
The behaviour of an in- | -viscid | fluid
Is quite different from | that of | one with low vis- | -cosity.
