explain the principle of regenerative cooling
Answers
Regenerative cooling is a method of cooling gases in which compressed gas is cooled by allowing it to expand and thereby take heat from the surroundings. The cooled expanded gas then passes through a heat exchanger where it cools the incoming compressed gas.
Regenerative cooling is a method of cooling gases that involves allowing compressed gas to expand and absorb heat from the environment. The cooled expanded gas then cools the entering compressed gas as it passes through a heat exchanger.
For mos gases, the Joule-Thomson cooling is relatively minimal. Thus, for air at 20 degrees Celsius, the pressure on both sides is 50 atmospheres and 1 atmosphere, respectively. The temperature drops by 11.7 degrees Celsius. Even at 210 atmospheres, the temperature drops just 42 degrees Celsius. However, by going through a regenerative process, the effect is amplified.
Before the incoming gas reaches the nozzle, a portion of the gas that has undergone Joule-Thomson expansion and has gotten chilled is used to cool other portions of the incoming gas. The cooling effect can be multiplied many times this way. Regenerative cooling refers to the cumulative process of constantly cooling a gas.
