Two-Phase Flow Field Simulation of Horizontal Steam Generators

Numerical Investigation of Shell-Side Flow Behavior and Vapor Distribution in Waste Heat Boilers

“…To partially solve this problem, in the past, multiphase CFD simulations of STHEs have been carried out using a coarse-grained porous medium approximation, , where the tube bundle region is treated as a porous region with some flow resistance that is a function of the pattern and pitch. The porous media approximation has been applied to study boiler systems by McNeil, − Maslovaric, and Rabiee , with R113 and water. The simulation results showed mixed levels of accuracy in comparison to experimental data, where the pressure drop results for a R113 two-dimensional boiler showed good agreement while the vapor fraction showed only qualitative agreement with the experimental results.…”
