Explanation:
- Pressure drag vs. Friction drag:
When the pressure drag over a body is large compared to the friction drag, it means that the majority of the drag force is caused by the pressure difference around the body rather than the shear stress on the body surface.
- Bluff body:
A bluff body is a shape that creates a large wake and separation region behind it, leading to significant pressure drag. Bluff bodies have a high drag coefficient due to the large pressure drag component.
- Characteristics of a bluff body:
1. Bluff bodies have a rounded shape with a blunt leading edge.
2. They create a large wake region behind them, which increases the pressure drag.
3. Examples of bluff bodies include cylinders, spheres, and square blocks.
- Effects of a bluff body shape:
1. The large pressure drag on a bluff body results in a higher overall drag force compared to a streamlined body.
2. Bluff bodies are less aerodynamic and experience more drag at higher velocities.
3. They are commonly used in applications where drag force is not a significant concern, such as buildings, vehicles, and flow control devices.
Therefore, when pressure drag over a body is large compared to friction drag, the shape of the body is that of a bluff body.
