Normal shock index
WebIntro to Normal Shocks • A normal shock wave is a shock with the wave front normal to the freestream flow. • Normal shocks occur, for example, in supersonic internal and jet flows. • Studying a normal shock is the first step in gaining an understanding of shock waves. • We will apply one-dimensional equations to derive relations for a ...
