Upper-convected time derivative
text:
In continuum mechanics, including fluid dynamics, an upper-convected time derivative or Oldroyd derivative, named after James G. Oldroyd, is the rate of change of some tensor property of a small parcel of fluid that is written in the coordinate system rotating and stretching with the fluid. The operator is specified by the following formula: where: A ▽ is the upper-convected time derivative of a tensor field A D D t is the substantive derivative ∇ v = ∂ v j ∂ x i is the tensor of velocity deriva
