Résumé

Film boiling heat transfer coefficients were measured on 10, 30 and 50 mm long vertical plates in subcooled He II for bulk liquid temperatures from 1.8 to 2.1 K. A film boiling model on a vertical plate in subcooled He II was presented based on convection heat transport in the vapour film, radiation heat transport, and heat transport in He II. The numerical solutions of the model were obtained and an equation which can express the numerical solutions within plus or minus 5% difference was derived. The equation predicted well the experimental data for lower deltaT range but significantly under-predicted the data for higher deltaT. A correlation of film boiling heat transfer including radiation contribution was presented by modifying the equation based on the experimental data. This correlation can describe the experimental data within plus or minus 20% difference. [Reprinted with permission from Elsevier. Copyright, 2007].
