## 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.
