| Abstract: | Boiling heat transfer data for water, methanol and their seven binary mixtures are presented. The heat transfer section consisted of an electrically heated stainless steel tube of 25.56 mm i.d. and 1900 mm length. The heat flux values ranged from 4.1 to 4.30 kW/m2. The liquid submergence levels were maintained at 100, 75: 50 and 30 percent. All the data were generated at atmospheric pressure. A significant reduction In the heat transfer coefficient is observed for binary mixtures attributable to the effect of mass diffusion on heat transfer. Possible reasons for the low heat transfer rates in mixtures are suggested in relation to bubble growth and nucleation. |
