✦ Synopsis

Based on the principle qfminimum volume, an optimum shape offn is proposed in this study. The outer appearance is essentially like a cylindrical.fin and the excavated part is in the inner portion qf the@. First, the surf&e heat,flux is assumed to follow a power-law dependence. With the aid of one-dimensional hnalysis, the temperature distributions and the projiles of the excavation hole are catculatedfor various single heat transj2r modes. Secondly, the boiling curve of isopropyl alcohol on copper surface is used as an input to the model. The base temperature in thejilm boiling rqgime is taken and the optimum geometry is presented. Finally, the eficiency based on the volume and heat duty is discussed.
