point de bulle

CONT: Les gaz dissous contenus dans le fluide géothermal se séparent de la phase liquide en-deça d'une certaine pression, appelée «point de bulle». Ce paramètre permet de déterminer la pression minimale à maintenir dans le réseau [...] afin de prévenir l'ébullition du fluide et le risque d'un éclatement de tuyau.

CONT: ... if a certain volume of liquid is held at constant pressure but the temperature is increased, a point is reached at which bubbles of gas begin to form in the liquid. That point is the bubble point of the liquid. Similarly, if a certain volume of liquid is held at a constant temperature but the pressure is reduced, the point at which gas begins to form is the bubble point.
