Inviscid flow is a theoretical concept in fluid dynamics that describes the flow of a fluid with zero viscosity.

Some key features of inviscid flow include:
No energy is lost due to internal friction
The flow is reversible
No wake is formed behind a body placed in an inviscid flow
Boundary layers are absent in an ideal inviscid flow 

A fluid that is incompressible and has no viscosity is known as an ideal or inviscid fluid. Ideal fluids are incompressible, which means the density is constant. They are also irrotational, which means the flow is smooth, with no turbulence. 

Some examples of inviscid flow include:
Flow around an airplane wing
Upstream flow around bridge supports in a river
Ocean currents
Superfluids, such as helium-4 

Flow at speeds below 0.3 times the speed of sound can be considered to be incompressible. 

Incompressible flow is a flow in which the density of a fluid remains constant. It is also known as isochoric flow, which comes from the Greek words isos-choros which means "same space/area". 

Incompressible flow is often assumed because density changes are usually negligible. A common criterion for classifying compressible and incompressible flows is when the density change is 5% or less. 
In an incompressible fluid, changes in pressure do not cause any corresponding changes in density. This means that the fluid is unable to support sound waves. 

Incompressible flow modeling is used for many applications in CFD, including:
Flow through valves and water turbines
Ventilation in a parking lot
Aerodynamics of vehicles 

Incompressible flow over airfoils is important for understanding the airflow around airfoils. This is important for determining the best materials and shapes for wings and propellers for the speed range in which the aircraft will operate.
