Shock diamonds are the bright areas seen in the exhaust of this statically mounted Pratt & Whitney J58 engine on full afterburner.. Shock diamonds (also known as Mach diamonds or thrust diamonds, and less commonly Mach disks) are a formation of standing wave patterns that appear in the supersonic exhaust plume of an aerospace propulsion system, such as a supersonic jet engine, rocket, ramjet ...
A vapor cone (also known as a Mach diamond, [1] shock collar, or shock egg) is a visible cloud of condensed water that can sometimes form around an object moving at high speed through moist air, such as an aircraft flying at transonic speeds. When the localized air pressure around the object drops, so does the air temperature.
At the minimum flow area, or throat, a normal or plane shock occurs. The flow area then increases for subsonic compression, or diffusion, up to the engine face. The position of the cone within the intake is usually controlled automatically to keep the plane shock wave correctly located just downstream of the throat.
Diamond is a solid form of the element carbon with its atoms arranged in a ... the shock wave can produce high enough temperatures and pressures for ...
The lead sentence actually errs slightly when it implies "Mach disk" is a synonym for shock diamond, which it isn't exactly. The geometry of expanding flow from a volcanic eruption doesn't look like it is conducive to the pattern of expansion and compression shock which forms a repeating pattern.
Diamond is also less slippery than Morton, a subtlety that chefs notice pinch after pinch. What’s more, Diamond tends to adhere better to food, again because of the pyramid-shaped grain.
Alcohol is used as a social lubricant, maybe more so as holiday festivities approach. But drinking carries health and other risks. Here are five tips to make it safer.
1. Tennis Ball. Tennis balls are so useful that you may want to buy some to keep around the house even if you don’t play. For example, half a tennis ball can help screw open tight caps.
