What is Fluid Kinematics?
Fluid
mechanics one branch is fluid kinematics. It
deals with the study of velocity and acceleration of the particles of fluids in
motion and their distribution in space without considering any force or energy
involved. The motion of fluid can be
described fully by an expression describing the location of a fluid particle in
space at different time’s thus enabling determination of the magnitude and
direction of velocity and acceleration in the flow field at any instant of
time.
Methods of Fluid Motion:
There
have two methods for fluid motion.
a. Eulerian method:
In this method, the observer concentrates on a point
in the fluid system. Velocity acceleration and other characteristics of the
fluid at that particular point are studied. Eulerian method is exclusive method
in flid mechanics because of it’s mathematical simplicity.
b. Langrangian method:
In this method the observer concentrates on the
movement of a single particle. The path taken by the particle and the changes
in its velocity and acceleration are studied.
