FURTHER REMARKS ON THE STABILITY OF BOILING HEAT TRANSFER. Report 58-5

摘要: An analytical expression is presented which permits the prediction of maximum nucleate heat flux in pool boiling saturated or subcooled liquids. The numerical values empirical constants appear Kutateladze and Borishanskii criteria for burnout'' are derived from theory. function appears correlation Griffith also derived. hitherto unexplored features transition boiling, i.e., hydrodynamic instability, well defined geometrical configuration frequency dependence described, supported by experimental evidence, used as basis work. peak shown to be limited combined effects Taylor Helmholtz instabilitiess whereas minimum transitional effect instability ony. analysis leads conclusion that because statistical nature ddsturbances bandwidth'' unstable wavelengths govern process, an inherent uncertainty exists determining exact value at burnout.'' width this range plus minus 14%. often noted poor reproducibility data on can bemore » inferred, therefore, analysis. reason attacks upon problem, based considerations bubble agitation other characteristics, have not been successful discussed. literature has conclusively surface conddtions play dominant role superheat accompanying a given flux. reveals, addition, even if nucleating characteristics were known problem could still solved these mechanism occurs fluid away surface. extension flow systems briefly (auth)« less
