Development, Evaluation and Improvement of Correlations for Interphase Friction in Gas-Liquid Vertical Upflow
… of finding an improved method of modelling the interphase friction in two-phase vertical flow in nuclear thermal-hydraulic codes. An improved method of modelling interphase friction should allow for better prediction of pressure gradient, void fraction and the phasic velocities. Data has been …

Modeling Two-Phase Flow in the Downcomer of a Once-Through Steam Generator using RELAP5/MOD2
… RELAP5/MOD2 have shown that RELAP over-predicts interphase friction. However, all of those studies focused on heated two-phase upflow, whereas the downcomer is modeled as adiabatic two-phase downflow. In this study, it is found that the original slug drag model for RELAP5/MOD2 developed by Idaho …

Using Simulink to Develop a One-Dimensional, Two-Phase Fluid Model
… a cross-sectional area change. Rough models of interphase heat transfer and interphase friction are included. Currently, phase change is not modeled in the simulation Also, a single-fluid model was developed before the two-fluid model, as an intermediate step in developing the two-fluid model. …

Analysing aspects of the performance of an ironblast furnace
… to the gas momentum, so as to account for the interphase friction caused by the packed bed. This enabled the prediction of the cohesive zone geometry, together with the active coke and stack, thus providing an important step for a successful analysis. The availability of multi-phase codes to …

Computer simulation of fire-sprinkler interaction
… account the physics involved in this process, interphase friction or drag was considered. Furthermore, due to the large difference in temperatures between the hot gases and the cold water droplets it was necessary to introduce interphase heat transfer. Due to the subsequent evaporation of the …
