A dimensionless number used in the study of forced convection which gives a measure of the ratio of the total heat transfer to conductive heat transfer, and is equal to the heat-transfer coefficient times a characteristic length divided by the thermal conductivity. 2, record 1, English, - Nusselt%20number

Record number: 1, Textual support number: 1 CONT
Le nombre Nu est égal au rapport de la chaleur effectivement transportée à travers le système turbulent à la chaleur [plus faible] qui serait transportée s'il n'y avait que de la conduction, pas de mouvement convectif du fluide. 4, record 1, French, - nombre%20de%20Nusselt
Record number: 1, Textual support number: 1 OBS
Lorsque le chauffage est faible, c'est-à-dire aux faibles valeurs de Ra, le nombre de Nusselt vaut un, ainsi en régime turbulent, Nu peut être beaucoup plus grand que un : la chaleur est essentiellement transportée par convection. 4, record 1, French, - nombre%20de%20Nusselt

Moyennant un choix approprié de grandeurs caractéristiques, il peut représenter le rapport entre la chaleur réellement transférée et la chaleur qui serait transférée dans les mêmes conditions par conduction pure. 3, record 1, French, - nombre%20de%20Nusselt
