Abstract

This chapter provides a brief review of the equations of fluid flow. The one-dimensional forms of the equations that apply to non-viscous flow are presented in both plane and spherical geometry. The Eulerian and Lagrangian descriptions of fluid motion are briefly outlined. Since this book deals with shock waves in air, which is considered to behave as a perfect gas, those elements of thermodynamics that apply to perfect gases and that have relevance to fluid motion are also presented. The chapter concludes with a brief look at small amplitude disturbances and the speed at which they are propagated in air. The equations presented in this chapter are important for the subsequent chapters.
