convective term
(Or advective term.) Any term of the form V · ∇ζ where V is the velocity field, ∇ is the del-operator, and ζ is any field, vector, or scalar.
Thus, for example, 
is a convective acceleration. These are the nonlinear terms in Eulerian expressions for the rate of change of the dependent variables.
