FALLING FILM BOILING HEAT TRANSFER IN A VERTICAL TUBE |
| |
| Abstract: | The physical and mathematical models are proposed for the falling film boiling heat transfer, in which the effects of convective flow and nucleate boiling on film heat transfer coefficients are taken into account and the inhibition of liquid flow to the nucleate boiling in the film is considered. A good agreement is found between the value calculated by the models and the experimental one. |
