Normal acceleration in fluid-flow situations exists only when the flow is unsteady. Let's understand this in detail:
Definition of Normal Acceleration:
Normal acceleration is the change in velocity perpendicular to the direction of motion. In fluid mechanics, normal acceleration is the change in velocity perpendicular to the streamline direction.
Factors affecting Normal Acceleration:
The normal acceleration in fluid-flow situations is affected by the following factors:
1. Flow Unsteadiness: Normal acceleration exists only when the flow is unsteady. In steady flow, the velocity at any point remains constant over time, and hence there is no change in velocity perpendicular to the streamline direction.
2. Curved Streamlines: In a fluid flow with curved streamlines, the velocity changes direction, resulting in normal acceleration.
3. Three-Dimensional Flow: In three-dimensional flows, the velocity may change in all three directions. Hence, there can be normal acceleration in all three directions.
Conclusion:
Normal acceleration in fluid-flow situations exists only when the flow is unsteady. In steady flow or two-dimensional flow with straight and parallel streamlines, normal acceleration does not exist. However, in curved streamlines or three-dimensional flows, there can be normal acceleration.
