The phrase "active venting" is correct and usable in written English.
It can be used in contexts related to engineering, environmental science, or any situation where gases or fluids are being released intentionally from a system.
Example: "The active venting of gases from the reactor is crucial for maintaining safe pressure levels."
Alternatives: "controlled release" or "intentional venting".
Studies at vents have shown that settlement is greater near active venting, indicated by vigorous flow and/or high temperature of the emanating fluid, than away from flow.
However, due to the absence of active venting, the system that we are using at present is inadequate for non-isolated CABG operations and for valvular procedures.
Vesicomyidae clams harbor sulfide-oxidizing endosymbionts and are typical members of cold seep communities where active venting of fluids and gases takes place.
A possible improvement to the system is the use of a closed venous reservoir actively draining the systemic venous blood (by means of an external negative pressure) which could be used for active venting of the left-sided cardiac cavities.
The following equipment and techniques were applied in the control and MICPB groups: In the control group, an open circuit with a hard-shell reservoir receiving blood from the venous cannulation, an active venting from the aortic root, and all the surgical field suctions were directly sent to the venous reservoir.
During the fall of 2014, the summit lake practically disappeared and the crater was substantially occupied by an active vent with moderate to sustained Strombolian activity (such as the eruption of November 27, 2014).
A further increase in the activity will cause the transition to Strombolian activity with the ejection of juvenile materials from active vents.
Halema'uma'u Crater, located within Kilauea's caldera, is the volcano's most active vent.
The floor, paved with recent lava flows, contains the Halema'uma'u ("Fern House") Crater, an inner crater that is Kilauea's most active vent.
It has an area of 257 square miles (665 square km) and is known for its two active vents, Marum (4,167 feet [1,270 metres]) and Benbow (3,802 feet [1,159 metres]), which sit inside a caldera thought to have collapsed during a major eruption around 100 ce.
(D) Distance from active vent.
