No Slip condition in an Inviscid Fluid

In summary, the No Slip condition is a fundamental concept in fluid mechanics that states that the fluid at a solid boundary will have zero velocity relative to the boundary. It is important in understanding fluid behavior near solid boundaries and is used in many engineering applications. It only applies to viscous fluids and if violated, can lead to turbulent flow and energy losses. In certain cases, it can be modified or altered, such as in microfluidic systems.

In an Inviscid fluid would the no slip condition exist?
If it didn't would it follow that the free stream velocity would exist at the wall ?.
If this was the case would surface roughness still present an orthogonal area upon which the kinetic energy of the fluid would interact causing a momentum change ?

No, the no slip condition does not exist in an inviscid fluid. The velocity at the wall would depend on the shape of the wall. If it was a flat plate, then yes, the velocity at the wall would be that of the free stream.
 

1. What is the No Slip condition in an Inviscid Fluid?

The No Slip condition is a fundamental concept in fluid mechanics that states that the fluid at a solid boundary will have zero velocity relative to the boundary. This means that the fluid molecules in contact with the boundary will have the same velocity as the boundary itself.

2. Why is the No Slip condition important?

The No Slip condition is important because it helps us understand the behavior of fluids near solid boundaries. It is a key concept in studying fluid flow and is used in many engineering applications, such as designing aircraft and analyzing blood flow in arteries.

3. Does the No Slip condition apply to all fluids?

No, the No Slip condition only applies to viscous fluids, which have a tendency to stick to solid boundaries. Inviscid fluids, on the other hand, have no viscosity and therefore do not exhibit the No Slip condition.

4. What happens if the No Slip condition is violated?

If the No Slip condition is violated, it can lead to turbulent flow and energy losses in the fluid. This can have negative effects in engineering applications, such as decreased efficiency in pipes and increased drag on vehicles.

5. Can the No Slip condition be modified or altered?

Yes, in certain cases, the No Slip condition can be modified or altered. For example, in microfluidic systems, the fluid may exhibit slip behavior, where the fluid molecules near the boundary have a non-zero velocity relative to the boundary. This can be taken into account in the design and analysis of such systems.
