What Adiabatic Flow Means?

[¦ad·ē·ə¦bad·ik ′flō] (fluid mechanics) Movement of a fluid without heat transfer.

Is flow adiabatic?

… flow is said to be adiabatic, and β_S is needed instead. (The S refers to entropy, which remains constant in an adiabatic process provided that it takes place slowly enough to be treated as “reversible” in the thermodynamic sense.)

What is adiabatic process example?

An example of an adiabatic process is the vertical flow of air in the atmosphere; air expands and cools as it rises, and contracts and grows warmer as it descends. Another example is when an interstellar gas cloud expands or contracts. Adiabatic changes are usually accompanied by changes in temperature.
