Austrian scientists from the Institute of Fluid Mechanics at the Vienna University of Technology spoke about the physical secrets of opening a bottle of champagne. Their research reveals how a supersonic shock wave, comparable to a powerful aircraft, pushes gas out of the bottle at speeds of up to 400 meters per second at a surprisingly low temperature of -130°C, much lower than at the North Pole.
Writes about this Daily Mail.
The team used sophisticated computer modeling to calculate the behavior of the stopper and the flow of CO2 when the bottle is opened. It turned out that the plug flies out at a speed of about 20 m/s, while the gas flow reaches 400 m/s, making it supersonic. This is a phenomenon similar to what occurs in supersonic aircraft and rockets.
In addition, the study found that opening a bottle of champagne is accompanied by a sonic pop, which is explained by two different effects: the rapid expansion of the cork and the formation of a supersonic gas jet. These discoveries may be important for understanding other phenomena associated with gas flows, for example, in the development of ballistic missiles and projectiles.
