Type of article: Article

Summary

FLUID-ELASTIC INSTABILITY IS WIDELY RECOGNIZED AS A MECHANISM WHICH CAN CAUSE RAPID FAILURE OF TUBES IN SHELL AND TUBE HEAT EXCHANGERS. THE SHELLSIDE FLOW VELOCITY IS COMMONLY CALCULATED FROM CONNORS' FORMULA PROVIDED THAT THE INSTABILITY FACTOR IS KNOWN. THE LITERATURE CONTAINS SEVERAL REPORTED VALUES, BUT THERE IS LARGE DISCREPANCY. THE PAPER DESCRIBES A SYSTEMATIC STUDY OF THE EFFECT OF TUBE LAYOUT ON THE INSTABILITY FACTOR FOR SIXTEEN TUBE BUNDLES. THE RESULTS SHOW THAT THE INSTABILITY FACTOR VARIES BY A FACTOR OF THREE. IT IS CONCLUDED WITH A COMPARISON OF THE RESULTS OF THE PRESENT STUDY WITH VALUES FROM THE LITERATURE.
