Circulation Flowrate - an overview | ScienceDirect Topics

In the 1950s, the development of a natural circulation water tube boiler was put into practical use, following the drum-type boiler. Since then, considerable knowledge of flow instability has been accumulated, but Münzinger [4] had already written about the flow instability related to the boiling phenomena in his literature in 1933.
