Numerical simulation of boiling heat transfer of a horizontal tube is important. It can provide insight into the modeling of boiling phenomena and help select the right models to predict heat transfer for industrial applications such as in kettle reboilers. In this study, heat transfer characteristics of convective boiling on the outside of a horizontal tube immersed in a large saturated liquid with upward velocity is studied numerically by using finite volume method with the mixture model in multiphase flow. Turbulence is modeled by the standard κ – ε model in mixture of multiphase. For different heat fluxes with different upward flow velocities, the local angular distribution of heat transfer coefficient and void fraction around the tube are presented. The results are compared with relevant experimental data.

Turbulent Natural Convection

A model for nucleate pool boiling heat transfer of binary mixtures has been proposed based on an additive mechanism. The contributing modes of heat transfer are (i) the heat transferred by microlayer evaporation, (ii) the heat transferred by transient conduction during the reformation of the thermal boundary layer, and (iii) the heat transferred by turbulent natural convection. The model takes into account the microroughness of the heating surface which has been defined quantitatively. The model compares satisfactorily with data obtained in the present study and in the literature. These data were obtained on a variety of heating surfaces such as a vertical platinum wire, a horizontal stainless steel tube and flat horizontal aluminium, and stainless steel surfaces (with various surface finishes) thereby demonstrating the validity of the model.
