The equation of flow acceleration is
where du/dt is the global acceleration, and ∂u/∂t and u ∂u/∂x are local and convective acceleration respectively.
And the heat conduction equation is
which is heat stored = net heat flux + heat generated.
My question is: why does the ∂T/∂t part in the heat conduction equation is partially differentiated, while the du/dt part in the flow acceleration isn't?
