THE INFLUENCE OF BUBBLY FLOW ON BOILING FROM A TUBE IN A BUNDLE.

Author(s) : CORNWELL K.

Type of article: Article

Summary

THE FORMS OF BUBBLY FLOW OCCURRING WITHIN A TUBE BUNDLE ARE DISCUSSED AND THE BOILING PROCESS IN THE BUNDLE IS NOTIONALLY DIVIDED INTO MECHANISMS DUE TO LIQUID FORCED CONVECTION, SLIDING BUBBLES AND NUCLEATION. A NOVEL EXPERIMENTAL ANALYSIS OF HEAT TRANSFER FROM A TUBE IN A BUNDLE INDICATES THE PREDOMINANCE OF THE SLIDING BUBBLE PART. THERE IS A VIRTUAL ABSENCE OF NUCLEATION IN A BUNDLE EXCEPT AT THE LOWEST TUBES INDICATING THAT, ONCE ENOUGH BUBBLES HAVE BEEN PRODUCED, THE OTHER MECHANISMS ARE SUFFICIENT TO TRANSFER THE HEAT FROM THE TUBES.
