Applications of Fluid Mechanics Presentation Assaignment

Definition of  Fluid Mechanics

Fluid mechanics is the branch of physics concerned with the mechanics of fluids and the forces on them. It has applications in a wide range of disciplines, including mechanical, civil, chemical and biomedical engineering, geophysics, oceanography, meteorology, astrophysics, and biology.

Classification of Fluid Mechanics 

•Ideal fluid

Ideal fluid is basically defined as a fluid which will be incompressible and in which viscosity will be zero.If we talk practically, there will be no existence of ideal fluid and therefore ideal fluid is an imaginary fluid only

•Real Fluid

Real fluid is basically defined as a fluid which will be incompressible and in which

 viscosity will not be zero. There will be viscosity in such fluids

•Example:•Water, Kerosene, Petrol, Air

Classification of Fluid Mechanics 

Newtonian fluid

Newtonian fluid is basically defined as a fluid in which shear stress will be directly proportional with the velocity gradient.We can also say that a fluid which follows the Newton’s law of viscosity will be termed as Newtonian fluid.

Example:

Water, Air, Benzine etc

Non- Newtonian fluid

Non- Newtonian fluid is basically defined as a fluid in which shear stress will not be directly proportional with the rate of shear strain or velocity gradient.We can also say that a fluid which does not follow the Newton’s law of viscosity will be termed as Non- Newtonian fluid.

Example:

Plaster, Flubber, Slurries and Pastes etc.

Classification of Fluid Mechanics 

Ideal Plastic fluid

Ideal Plastic fluid is basically defined as a fluid in which shear stress will be more than the yield value and shear stress will be directly proportional with the rate of shear strain or velocity gradient.

Incompressible fluid

If density of a fluid will not be changed with change in external pressure or force, then that fluid will be termed as Incompressible fluid. Liquids will be considered as incompressible fluid. Therefore, hydraulic accumulators are used to develop the nature of compressibility in hydraulic systems.

Classification of Fluid Mechanics 

Compressible fluid

If density of a fluid will be changed with change in external pressure or force, then that fluid will be termed as compressible fluid. Gases will be considered as compressible fluid.
