Fluid dynamics investigates the flow of liquids and gases. Nonsticky fluids are the subject of this course, for which the basic equation is the Euler equation, which repesents the law expressing `force equals rate of change of momentum'. A subtlety arises because the rate of change here applies to that following fluid particles, not at a fixed point in space. It is necessary to use the convective derivative: a time derivative following the fluid. The forces driving the motion can be external, such as gravity, or internal, arising from pressure. The fluid motion is often incompressible and irrotational, in which case the flow can be expressed in terms of potentials and the motion is governed by Laplace's equation. The suitations investigated in this course include simple flows in channels, jets, sources and sinks, bubbles, waves and aircraft wings.
