Types Of Fluid Flow

Types Of Fluid Flow:-

 1) Steady & Unsteady Flows.                                 2) Uniform & Non-uniform Flows.                     3) Laminar & Turbulent Flows.                             4) Compressible & Incompressible Flows.           5) Rotational & Irrotational Flows.                     6) One , Two & Three Dimensional Flows.

1:) Steady & Unsteady Flows:- 

(a): Steady Flows:- In which the fluid Characteristics Like velocity, pressure, density , etc. At a Point do not change with time.

(b): Unsteady Flow:- In which the fluid velocity , pressure or density at a point changes with respect to time.

2:) Uniform & Non-uniform Flow :- 

(a): Uniform Flow:- In which the velocity at given time does not change with respect to space ( length of direction of the flow ).

(b): Non-Uniform Flow:- In which the velocity at any time changes with respect to space. Changing in space

3:) Laminar & Turbulent flows:- 

(a): Laminar Flow:- in which the fluid particles move along well defined paths or stream line. 

(b): Turbulent Flow:- fluid moves in very irregular paths or zig – zag Way. velocity at a point fluctuates.

4:) Compressible & Incompressible Flows:-          (a): Compressible Flows:- In which the density of the fluid changes from point to point. The density is not constant for the fluid. 

(b): Incompressible Flows:- In which the density of fluid changes from point to point. the density is constant for the fluid.

5:) Rotational & Irrotational Flows:-

(a): Rotational Flow :-In which the fluid particles while flowing along stream lines, Also rotate about their own axis.

(b): Irrotational Flow:- In which the fluid particles while flowing along stream lines, do not rotate about their own axis.

6:) One Dimensional Flow:-

(a): One , Two & Three Dimensional Flows:- In which the flow parameter such as velocity is a function of time and one space co-ordinate only.

(b): Two Dimensional Flow:- In which the velocity is a function of time and two rectangular space co-ordinates.

(c): Three Dimensional Flow:- In which the velocity is the function of time and Three mutually perpendicular directions.
