What is Compressible Fluid Flow?
Compressible fluid flow refers to the behavior of fluids (primarily gases) when their density changes significantly due to pressure or temperature variations. Unlike incompressible flows, where the density remains constant, compressible flows require different equations and methods for analysis. The key characteristics of compressible fluid flow include:
- Density variations: Changes in pressure and temperature lead to changes in density.
- Shock waves: High-speed flows can produce shock waves, which are abrupt changes in pressure and density.
- Applications: Compressible flow is relevant in aerodynamics, gas turbines, and rocket propulsion.
Fundamental Equations of Compressible Flow
The analysis of compressible fluid flow is primarily based on the conservation equations of mass, momentum, and energy. These equations can be derived from the fundamental principles of fluid mechanics and thermodynamics:
1. Continuity Equation: This equation ensures mass conservation in a control volume.
\[
\frac{\partial(\rho)}{\partial t} + \nabla \cdot (\rho \mathbf{u}) = 0
\]
2. Momentum Equation: This equation describes the conservation of momentum.
\[
\frac{\partial(\rho \mathbf{u})}{\partial t} + \nabla \cdot (\rho \mathbf{u} \mathbf{u}) + \nabla p = 0
\]
3. Energy Equation: This equation accounts for the conservation of energy in the flow.
\[
\frac{\partial E}{\partial t} + \nabla \cdot (E \mathbf{u}) + p \nabla \cdot \mathbf{u} = 0
\]
Where:
- \( \rho \) is the fluid density,
- \( \mathbf{u} \) is the velocity vector,
- \( p \) is the pressure,
- \( E \) is the total energy per unit volume.
These equations form the basis for analyzing compressible flow phenomena, including isentropic flow, shock waves, and expansion fans.
