What is Fluid Dynamics?
Fluid dynamics is a branch of physics that focuses on understanding the motion, behaviour, and interactions of fluids. It involves studying the forces acting on fluids, their response to external stimuli, and the resulting flow patterns. Fluid dynamics encompasses both fluid statics, which deals with fluids at rest, and fluid kinematics, which analyses fluid motion without considering the forces causing the motion.
Principles of Fluid Dynamics
a. Conservation of Mass: The principle of conservation of mass states that the mass of a fluid remains constant within a closed system. This principle allows us to analyse the continuity of fluid flow and understand how fluid mass is distributed in a given system.
b. Conservation of Energy: The principle of conservation of energy states that the total energy of a fluid, comprising kinetic energy, potential energy, and internal energy, remains constant in the absence of external work or heat transfer. This principle aids in understanding the energy changes within a fluid system.
c. Conservation of Momentum: The principle of conservation of momentum states that the total momentum of a fluid system remains constant in the absence of external forces. This principle is essential for analysing fluid motion and the forces acting on fluids.
