Abstract: In this study, heat fluxes qc for condensation from steam and air mixtures on vertical flat plates were evaluated by using existing experimental data and qc correlations, in order to provide one of boundary conditions for ...

Abstract: A prediction system with a oneregion (1R) model was developed to predict water temperature in a spent fuel pit (SFP) after the shutdown of its cooling systems based on threedimensional (3D) thermalhydraulic behavior computed ...

Abstract: The structural integrity of the containment vessel (CV) for a pressurized water reactor (PWR) plant under a lossofcoolant accident is evaluated by a safety analysis code that uses the average temperature of gas phase in ...

Abstract: Onedimensional (1D) sensitivity computations were carried out for air–water countercurrent flows in a 1/15scale model of the hot leg and a 1/10scale model of the pressurizer surge line in a pressurized water reactor (PWR) ...

Abstract: The method for predicting countercurrent flow limitation (CCFL) and its uncertainty in an actual pressurizer surge line of a pressurized water reactor (PWR) using 1/10scale air–water experimental data, onedimensional ...

Abstract: One-region (1-R) sensitivity computations with the annular-flow model were carried out for countercurrent flow limitation (CCFL) at a sharp-edged lower end in vertical pipes to generalize the prediction method for CCFL ...

Abstract: Wall functions are generally used in a turbulent analysis with a computational fluid dynamics (CFD) code and large computation cells. The logarithmic law based on the analogy between momentum, energy, and mass transfer is ...
