Component-scale modeling of boiling is predominantly based on the Eulerian–Eulerian two-fluid approach. Within this framework, wall boiling is accounted for via the Rensselaer Polytechnic Institute (RPI) model and, within this model, the bubble is

This paper presents the results of large-eddy simulation (LES) of a downward wall jet that encounters an upward flow in a vertical rectangular channel, named negative buoyant fountain (NBF). The downward jet fluid has higher temperature than the oppo

Abstract Water boiling control evolution of natural geothermal systems is widely exploited in industrial processes due to the unique non-linear thermophysical behavior. Even though the properties of water both in the liquid and gas state have been ex
