Due to the inherent mathematical complexity of the system of equations, simplifying assumptions are made to obtain a numerical solution. The system of equations is solved numerically to obtain values of the unknown quantities at each subsequent axial location. Derived quantities like void fraction and heat transfer coefficient are calculated at each axial location. The calculation is terminated when the void fraction reaches a value of 0.6, the upper limit of IAFB. The results obtained agree with the experimental trends observed. Void fraction increases along the heated length, while the heat transfer coefficient drops due to the increased resistance of the vapor film as expected.The two-fluid model predictions of heat transfer in IAFB are based on the concept of reduction of the number of degrees of freedom of the system. The model ... The model predictions were compared to experimental data from four fluids (water, Freon-12, Freon-22 and Freon-134a). Instead of developing closure relationships for each unknown quantity, Hammouda et. al. attempt to provide physically sound anbsp;...
