Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe total differential D/Dt is known as the material or substantial derivative with respect to time.
The first term ∂/∂t in the right-hand side of is known as a temporal or local derivative which expresses the rate of change with time, at a fixed position. The last three terms in the right-hand side of are together known as a convective derivative which represents the time rate of change due to change in position in the field.
| Type of Flow | Temporal | Convective |
| Steady Uniform flow | 0 | 0 |
| Steady non-uniform flow | 0 | exists |
| Unsteady Uniform flow | exists | 0 |
| Unsteady non-uniform flow | exists | exists |
So total acceleration can be zero.
