Abstract :
nimprovedlook-uptableforfilm-boilingheat-transfercoefficientshasbeenderivedforsteam–waterflowinsideverticaltubes.Comparedtoearlierversionsofthelook-uptable,thefollowingimprovementsweremade:
•
Thedatabasehasbeenexpandedsignificantly.Thepresentdatabasecontains77,234film-boilingdatapointsobtainedfrom36sources.
•
Theupperlimitofthethermodynamicqualityrangewasincreasedfrom1.2to2.0.Thewiderrangewasneededasnon-equilibriumeffectsatlowflowscanextendwellbeyondthepointwherethethermodynamicqualityequalsunity.
•
Thesurfaceheatfluxhasbeenreplacedbythesurfacetemperatureasanindependentparameter.
•

•
Thetableentriesatflowconditionsforwhichnodataareavailableisbasedonthebestoffivedifferentfilm-boilingpredictionmethods.
