Abstract

In this study, the heat transfer coefficient of the pool boiling is evaluated in the nuclear region for the fluid at different concentrations of water-ethanol solution on a horizontal cylinder at 1 atm. For this purpose is examined the diameter of the growing bubble of water-ethanol solution in a heat flux range of 1 to 60 kW.m^-2 in different concentrations on the horizontal cylinder of stainless steel. The results show that by an increase in heat flux, bubble diameter increases. The diameter of the bubbles created in heat flux is examined and compared with different dynamic models that according to the calculated average error of the model. Hamzehkhani model has better consistency with the experimental data. Recently, optimization methods have been widely used in fuzzy equilibrium calculations. Among these methods, genetic algorithms can be used to calculate the binary interaction components of activity coefficient patterns in equilibrium systems. The equations and relations of previous for the solution have a high error in predicting the heat transfer coefficient, so using the obtained data and applying the genetic algorithm. A newer experimental equation is presented which has a good fitting with the experimental data.
