, 1-FLUID KINEMATICS: Introduction
Kinematics is the branch of mechanics that deals with quantities involving
space and time only. It treats variables such as displacement, velocity,
acceleration, deformation, and rotation of fluid elements without referring
to the forces who generates the motion.
Kinematics therefore essentially describes how the motion appears.
The objectives of this section will be:
• Lagrangian and eulerian descriptions of fluid motion; material derivative
• Pathlines, streakline, and streamlines; streamtubes
• Local analysis of the fluid motion, linear and angular deformation of the
fluid element
• Space variability: One- two- and three-dimensional flows
• Flow regimes (laminar and turbulent flows)
