Webfluid particle. The material derivative has two parts. First, ∂F/∂t, called the local derivative, represents the rate of change at any fixed point. For steady flow, ∂/∂t = 0. The remaining terms, u∂F/∂x + v∂F/∂y + w∂F/∂z, are called the advective derivative, because they record changes in F which arise as the fluid element ...

WebTechnically, the symmetry of second derivatives is not always true. There is a theorem, referred to variously as Schwarz's theorem or Clairaut's theorem, which states that symmetry of second derivatives will always hold at a point if the second partial derivatives are continuous around that point.
