Fluid Dynamics Basics Quiz

Study Notes

Fluid Dynamics

Fluid Dynamics is the study of fluid in motion.
Force (F) is equal to mass (m) times acceleration (a): F = m*a

Physical Quantities of Flow

Velocity (V) is a physical quantity of flow.
Pressure (P) is a physical quantity of flow.
Density (ρ) is a physical quantity of flow.
Temperature (T) is a physical quantity of flow.
Acceleration (a) is a physical quantity of flow.

Lagrangian and Eulerian Systems

Lagrangian system: describes the fluid motion in terms of the fluid's position over time.
Eulerian system: describes the fluid motion in terms of the fluid's velocity, pressure, density, temperature, and acceleration at a fixed point in space.
The Eulerian system is often used in fluid dynamics.

Eulerian System

Velocity (V) is a function of position (x, y, z) and time (t): V = V(x, y, z, t)
Pressure (P) is a function of position (x, y, z) and time (t): P = P(x, y, z, t)
Density (ρ) is a function of position (x, y, z) and time (t): ρ = ρ(x, y, z, t)
Temperature (T) is a function of position (x, y, z) and time (t): T = T(x, y, z, t)
Acceleration (a) is a function of position (x, y, z) and time (t): a = a(x, y, z, t)

Governing Equations of Fluid Flow

The governing equations of fluid flow, heat and mass transfer are based on the following assumptions:
- Incompressible Newtonian fluid
- Two-dimensional and laminar flow
- Temperature-independent thermo-physical properties, except for density in the buoyancy force
- Negligible effects of radiation and viscous dissipation
The governing equations include:
- Mass conservation equation: ∂u/∂x + ∂v/∂y = 0
- Momentum conservation equations in x and y directions
