stagnation pressure

stagnation pressure
Danh từ

This term is a technical specification used primarily in fluid dynamics and aerodynamics. It describes the total pressure at a point where the fluid velocity is zero, typically at the tip of a pitot tube. It is distinct from static pressure, which is the pressure of the fluid as it moves, and dynamic pressure, which relates to the fluid's kinetic energy.

In practical application, the term is almost exclusively used in engineering and physics contexts. It is not used in general conversation to describe "stagnant" air or water in a biological or environmental sense, but rather refers to a specific mathematical sum of pressures in a flow field.

Ý nghĩa

Danh từstagnation pressure

The total pressure exerted on a fluid when it is brought to a complete stop isentropically, representing the sum of the static pressure and the dynamic pressure.

The pitot tube measures the stagnation pressure of the airflow to determine the aircraft's airspeed.
