Effect of Bubble Turbulence and Submergence on Onset of Boiling in Natural Circulation Loop

Analysis of incipience boiling was developed for five different types of organic liquids including water covering wide range of physical properties. Incipience in liquid films is influenced by turbulent eddies and liquid submergence. This approach utilizes physical parameters of commonly accepted incipience models and provides a means of correcting these models for the effect of turbulent eddies and submergence. The results predicted from the theoretical analysis are consistent with the experimental data, having average absolute relative error of 13.61 percent.
