ContentFluid Kinematics
Fluid KinematicsKinematics is the study of the velocity and acceleration of the fluid motion.
There are two methods to study the motion of fluid. One way can focus on fluid particles
by tracking their position vector, i.e.
Velocity FieldFluid property can be represented as a function of spatial coordinates in term of a field representation. For a fluid flow, it is also a function of time. ![]() When the velocity value of a location equals to zero, Acceleration FieldIn a fluid flow, the velocity of a particle is a function of
its location and time. Imply
imply
Since the equation can be used to describe any particle, the
acceleration field can be obtained from the velocity field as And the total acceleration can be expressed as
Since the total derivative operator
The total acceleration is therefore also called material acceleration. ©sideway ID: 100100002 Last Updated: 2/7/2010 Revision: 1 Latest Updated Links
