Shock wave heating
WebThe shock wave forms 90 degrees to the airflow and is known as a normal shock wave. Stability problems can be encountered during transonic flight, because the shock wave can cause the airflow to separate from the wing. The shock wave also causes the center of lift to shift aft, causing the nose to pitch down. In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium but is characterized by an abrupt, nearly discontinuous, change in … See more Shock waves can be: Normal At 90° (perpendicular) to the shock medium's flow direction. Oblique At an angle to the direction of flow. Bow Occurs upstream of the front (bow) of a blunt object when the … See more In elementary fluid mechanics utilizing ideal gases, a shock wave is treated as a discontinuity where entropy increases abruptly as the … See more Shock waves can form due to steepening of ordinary waves. The best-known example of this phenomenon is ocean waves that … See more Below are a number of examples of shock waves, broadly grouped with similar shock phenomena: Moving shock • Usually … See more The abruptness of change in the features of the medium, that characterize shock waves, can be viewed as a phase transition: the pressure-time … See more Oblique shocks When analyzing shock waves in a flow field, which are still attached to the body, the shock wave which is deviating at some arbitrary angle from … See more A shock wave may be described as the furthest point upstream of a moving object which "knows" about the approach of the object. In this description, the shock wave position is defined … See more
