  • Mach wave — In fluid dynamics, a Mach wave is a pressure wave traveling with the speed of sound caused by a slight change of pressure added to a compressible flow. These weak waves can combine in supersonic flow to become a shock wave if sufficient Mach… …   Wikipedia

  • Mach wave — A wave formed in front of a body when it is moving at the speed of sound. The waves do not move ahead of the body; they bunch up and form a Mach wave. A Mach wave is at right angles to the direction of movement of the body and is called a normal… …   Aviation dictionary

  • normal Mach wave — A wave formed in front of a body when it is moving at the speed of sound. The waves do not move ahead of the body; they bunch up and form a Mach wave. If a Mach wave is at right angles to the direction of movement of the body, the wave is called… …   Aviation dictionary

  • Mach line — A theoretical line representing the backsweep of a cone shaped shock wave made by an assumed infinitesimally small particle moving at the same speed and along the same flight path as that of an actual body or particle. This line, as represented… …   Aviation dictionary

  • Mach wavelet — Small shock waves, usually present in large numbers in boundary layers and around the surface of a supersonic body. The bow wave becomes progressively weaker as it gets farther from the aircraft, eventually becoming a very weak Mach wave. Also… …   Aviation dictionary

  • Mach number — (mathrm{Ma} or M) (generally pronEng|ˈmɑːk, sometimes IPA|/ˈmɑːx/ or IPA|/ˈmæk/) is the speed of an object moving through air, or any fluid substance, divided by the speed of sound as it is in that substance. It is commonly used to represent an… …   Wikipedia
