p-wave compression waves
11Lee waves — In meteorology, lee waves, are atmospheric standing waves. The most common form is mountain waves, which are atmospheric internal gravity waves. These were discovered in 1933 by two German glider pilots, Hans Deutschmann and Wolf Hirth, above the …

13Homogeneous Charge Compression Ignition — Homogeneous Charge Compression Ignition, or HCCI, is a form of internal combustion in which well mixed fuel and oxidizer (typically air) are compressed to the point of auto ignition. As in other forms of combustion, this exothermic reaction… …
14Mach 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… …
15longitudinal wave — Physics. a wave in which the direction of displacement is the same as the direction of propagation, as a sound wave. Cf. transverse wave. [1930 35] * * * ▪ physics wave consisting of a periodic disturbance or vibration that takes place in… …
16shock wave — 1. a region of abrupt change of pressure and density moving as a wave front at or above the velocity of sound, caused by an intense explosion or supersonic flow over a body. 2. a repercussion from a startling event or upheaval; series of… …
17Acoustic wave — An acoustic wave is a weak compression wave (meaning a small pressure change) that moves at the speed of sound. As opposed to a shock wave, the pressure change is continuous, and the wave is isentropic, meaning energy is conserved as it… …
18Medium wave — Main article: Medium frequency Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM broadcasting. For Europe the MW band ranges from 526.5 kHz to 1606.5 kHz[1] and in North America an extended MW… …
19expansion wave — In supersonic flow, expansion waves occur when bodies begin to narrow, making more space available. In passing through an expansion wave, air velocity increases, while temperature and pressures are reduced. A simple wave or progressive… …
