Does Ideal Fluid Exist

Ideal fluid do not actually exist in nature, but sometimes used for fluid flow problems. 2. Real fluid: Fluid that have viscosity(μ > 0) and their motion known as viscous flow.

Why do ideal fluids not exist?

The theory for the existence of a BL along a wall assumed a small but finite viscosity, that is a real fluid. The ideal inviscid flow has a discontinuity on the tangential velocity at the wall. … So ideal fluid does not form a boundary layer.

What is difference between ideal fluid and real fluid?

An Ideal fluid has no viscosity, and surface tension and is incompressible, However such fluid does not exist in nature and thus the concept of ideal fluid is imaginary. Real fluid is one which possesses viscosity, surface tension, and is compressible and can be seen in nature.
