Introduction and Thermodynamic and Fluid Mechanics Principles Relevant to Compressible Flow
摘要
This introductory chapter focuses on thermodynamic and fluid dynamics principles relevant to compressible flow. Section 1.1 introduces compressible flow to the readers. This is followed by Sect. 1.2, which describes the details and applications of thermodynamic principles involved in compressible flow including the ideal gas equation of state, ratio of specific heats, energy balance for isentropic flow, and the concept of stagnation enthalpy. Section 1.3 describes the continuity equation for compressible flow followed by Sect. 1.4, which derives the general momentum equation for flow through a constant-area duct.
