“…Chen et al (Chen et al, 2009) simulated the upward subcooled boiling flow of R113 in vertical tube by CFX code with user defined FORTRAN and investigated the influences of physical properties, bubble diameter and variable saturation temperature on the predicted results. Ose and Kunugi (Ose and Kunugi, 2011) developed a numerical solution for pool subcooled boiling simulation.…”

“…In deriving the accurate results from the wall boiling model applied to the analysis of various boiling problems, the most dominant parameters are,   ,   and . As these parameters vary according to diverse factors, they are generally derived empirically through experiments, and the correlations between these parameters have been studied widely (Kurul, 1990;Alglart, 1993;Alglart and Nylund, 1996;Tu and Yeoh, 2002;Lee et al, 2002;Koncar et al, 2004;Krepper et al, 2007;Chen and Cheng, 2009;Krepper and Rzehak, 2011;Nemitallah et al, 2015;Gu et al, 2017). Previous studies have been confined mostly to selecting the optimal combination of submodels (nucleation site density and bubble departure diameter models), which is suitable only for a specific pressure section of a pipe.…”

The demand for eco-friendly energy is expected to increase due to the recently strengthened environmental regulations. In particular, the flow inside the pipe used in a cargo handling system (CHS) or fuel gas supply system (FGSS) of hydrogen transport ships and hydrogen-powered ships exhibits a very complex pattern of multiphase-thermal flow, including the boiling phenomenon and high accuracy analysis is required concerning safety. In this study, a feasibility study applying the boiling model was conducted to analyze the multiphase-thermal flow in the pipe considering the phase change. Two types of boiling models were employed and compared to implement the subcooled boiling phenomenon in nucleate boiling numerically. One was the "Rohsenow boiling model", which is the most commonly used one among the VOF (Volume-of-Fluid) boiling models under the Eulerian-Eulerian framework. The other was the "wall boiling model", which is suitable for nucleate boiling among the Eulerian multiphase models. Moreover, a comparative study was conducted by combining the nucleate site density and bubble departure diameter model that could influence the accuracy of the wall boiling model. A comparison of the Rohsenow boiling and the wall boiling models showed that the wall boiling model relatively well represented the process of bubble formation and development, even though more computation time was consumed. Among the combination of models used in the wall boiling model, the simulation results were affected significantly by the bubble departure diameter model, which had a very close relationship with the grid size. The present results are expected to provide useful information for identifying the characteristics of various parameters of the boiling model used in CFD simulations of multiphase-thermalflow, including phase change and selecting the appropriate parameters.

“…The influences of heat flux profile in the axial direction were investigated while maintaining the same total power. Chen et al [11] performed a CFD study on vertical subcooled flow boiling of refrigerant-113 using the two-fluid model. Their results showed that the bubble boundary layer became thicker when the wall heat flux was increased.…”

Accurate evaluation of the location of onset of significant void (OSV) is particularly important in predicting the void fraction profile in the subcooled flow boiling. In this study, a Computational Fluid Dynamics (CFD) model based on a wall heat flux partition algorithm is presented. Good consistency between simulation results and available experimental data for void fraction, liquid temperature, and wall temperature is demonstrated for a given case. To further evaluate the feasibility of the CFD model in predicting the OSV condition, more simulations are performed under various operational parameters. The simulation results show that an acceptable prediction is observed in the inlet and outlet sections for the void fraction in all the cases compared with experimental data. In addition, the relative enthalpy of the flow at OSV decreases
