3 Introduction Gas Dynamics: Dynamics of Compressible Fluid Flow ??? Density Changes are Large ( ∆ρ > 5%) Example Applications: Aircraft - Gas pipeline at high pressure & temperature - Compressors and many others. A Fluid: Is a substance that deforms CONTINUOUSLY under the application of a shear stress (what about a solid ??) Scope of Fluid Mechanics: Fluid Mechanics is concerned with the study of any system in which a fluid is used such as; 1) Aircraft 2) Automobiles 3) Submarines 4) Rockets 5) Flow around buildings (sky scrapers ??.) 6) Shopping malls 7) All kinds of sports 8) Fluid machines; pumps, compressors, fans 9) Pipelines 10) Medical ….. heart , respiratory system , …
4 If Fluid is compressible, it is Gas Dynamics Basic Equations: Analysis of any system of compressible flow starts with the basic laws of fluid motion; 1) Conservation of mass 2) Newton's 2 nd law of motion 3) Principle of angular momentum 4) 1 st law of thermodynamics 5) 2 nd law of thermodynamics In addition, - Equation of state of a perfect gas - Relation between shear stress and rate of deformation of a fluid - Fourier law of heat conduction Concept of a Continuum : Matter Microscopic Macroscopic
