Nur syamira atikah bt ismail. I think maybe a fluid is a gas or liquid that, unlike a solid, flows to assume the shape of the container in which it is plains ccurs because a fluid . Im also don't understand it again..

# data[].attributes.body
Definition & comparison :

-Ideal fluid: Fluids that dont have viscosity, incompressible and also resistance to shear.

-Real fluid: Fluids that have viscosity, compressible and always be shear resistance.

The no-slip condition for viscous fluids assumes that at a solid boundary, the fluid will have zero velocity relative to the boundary.

I don’t understand much about the slip and no-slip condition part.

# data[].attributes.attachment_link.readable_text
When a viscous fluid flows over a solid surface, the fluid element adjacent to the surface attain the velocity of the surface,in other words,the relative velocity between the solid surface and the adjacent fluid particle is zero. Solid never allows fluid to flow faster than it.This phenomenon is known as no slip condition.

Particles close to a surface do not move along with a flow when adhesionis is stronger than cohesion . At the fluid-solid interface, the force of attraction between the fluid particles and solid particles (Adhesive forces) is greater than that between the fluid particles (Cohesive forces). This force imbalance brings down the fluid velocity to zero.

As with most of the engineering approximations, the no-slip condition does not always hold in reality.

For example, at very low pressure (e.g. at high altitude), even when the continuum approximation still holds there may be so few molecules near the surface that they "bounce along" down the surface.

Slip condition is opposite of no slip condition.

This may help you...Thankyou

Fluid is a substance which is capable of flowing OR Fluid is substance which deforms continuously under the influence of a shear or tangential force. OR The tendency to deform continuously is called fluidity and act of continuous deformation is called as flow.

Classification of fluids-

Fluids which don't have viscosity and are incompressible are termed as ideal fluid such fluid do not offer shear resistance.

Fluids which do posses viscosity are termed as real fluids. These fluids always offer shear resistance.

Real Fluid further classified into two types

1. Newtonian fluid- The fluids which obey Newton's law of viscosity are called as Newtonian fluids such fluids exhibit linear relationship between shear stress and rate of angular deformation. Eg. - water , air etc.

2. Non-Newtonian Fluid- Fluids which do not follow the linear relation between shear stress and rate of angular deformation are termed as Non Newtonian fluids. Hence for such fluids;

$$τ=constant×\bigg(\dfrac{dy}{dx}\bigg)^n.$$

Ideal Fluid

The Fluid which is non viscous or friction-less and in-compressible is called ideal fluid.

We assume that ideal fluid is perfect fluid but fluid without viscosity is not possible or does not exist in real world so this is only a imaginary fluid.

Real Fluid

All fluid comes under real fluid because all the fluid having viscosity, compression and surface tension in its properties with a little amount of force.

NO SLIP CONDITION IN VISCOUS FLUID -BASIC OF FLUID MECHANICS 11 - ANUNIVERSE 22

# data[].attributes.body
The no-slip boundary condition at a wall is always more accurate. You should use for blood flow in capillaries.

The slip wall condition is for cases where viscous effects at the wall are negligible and/or your mesh size is much bigger than the boundary layer thickness (so you’re not capturing the boundary layer effects anyway). The slip boundary is also the proper boundary condition for symmetry surfaces. You can verify that if you look at the equations COMSOL uses when you select Symmetry boundary condition.

Ideal fluid

• Definition: A fluid is said to be ideal if it is assumed to be both incompressible and non viscous.
• Its bulk modulus is infinite.
• ideal fluid has no surface tension.
• Ideal fluid is a substance which is unable to resist internal shear and tensile forces.
• Ideal fluid are imaginary and do no exist in nature.
• They have laminar (smooth)flow as shown in the figure.

Real fluid

• Definition: A fluid which is compressible, has viscosity and surface tension, is known as real fluid.
• Real fluids implies friction effects.
• They have turbulent flow as shown in the figure.
• Examples: kerosene, petrol, castor oil

# data[].attributes.body
Ideal fluid is one which is incompressible and having zero viscosity, and hence there is not shearing effect between adjacent layers of fluid. In general it's not possible and nonrealistic. Because all fluid are Real fluid. Real fluid possesses some viscosity and are compressible in nature.

# data[].attributes.body
1.Ideal fluid do not actually exist in nature but sometimes used for fluid flow problems
Real fluid: Fluid that have viscosity(μ > 0) and their motion known as viscous flow.

All the fluids in actual practice are real fluids.

Fluid dynamics:

we use ideal fluid in 2 equations :

1.Continuity equation

2.Bernoulli equation

3. Newtonian Fluids:

A real fluid in which the shear stress is directly proportional to rate of shear strain (or velocity gradient).

4. Non-Newtonian Fluid:

A real fluid in which the shear stress is not proportional to the rate of shear strain.

5. Ideal Plastic Fluid:

A fluid in which shear stress is more than the yield value and shear stress is proportional to the rate of shear strain (or velocity gradient).

In fluid dynamics, the no-slip condition for viscous fluids assumes that at a solid boundary, the fluid will have zero velocity relative to the boundary.

The fluid velocity at all fluid–solid boundaries is equal to that of the solid boundary.[1] Conceptually, one can think of the outermost molecules of fluid as stuck to the surfaces past which it flows. Because the solution is prescribed at given locations.
