...-solid interface, including capillary phenomena, is not well understood. This paper presents basic research evaluating the evaporation characteristics of droplets upon contact with metallic porous media featuring small pores under 1 mm. We conducted experiments using bronze or stainless steel porous...

.... The Euler-Euler two-fluid model was employed alongside the k-ω-based Shear Stress Transport (SST) turbulence model to separately model turbulence for each phase. The results reveal that lateral flow dynamics are significant as fluids traverse through the porous media, affecting pressure drops across layers...

... will also lead to high thermal stress of the tube sheet. Thus, a precise prediction of temperature distribution after tube plugging is essential for the safety and efficiency of HTGR OTSG. An in-house code for tube and shell side coupled thermal analysis of HTGR SG was developed based on porous media...

...-hydraulic calculation of pebble bed HTGRs and proposes a method for the two-dimensional (2-D) simulation using the commercial computational fluid dynamics (CFD) software ANSYS FLUENT. The pebble bed reactor core, fluid flow zones and control rod channels in the reflector are modeled with a porous media...

... with high accuracy 3D TH phenomena. In this paper a multiscale approach based on porous media (PM) is proposed to reduce the computational cost of the Core Simulator CFD model. Firstly, the PM hydraulic behavior is characterized by means of CFD simulations on the infinite lattice domain. Then PM are applied...

... fluid-structure coupling effects under excitations, so the calculation is computationally intensive. For such complex structures, the use of porous media models is an important means of structure simplification. The parameters of porous media are often calculated by CFD modeling, and the calculation...

... 08 04 2011 The present studied Pebble-Bed Reactor is a light-water cooled reactor that consists of millions of Micro-Fuel Elements, and the TRISO-coated fuel particles (MFE) fill the fuel assembly disorderly and form a porous media with internal heat source. Papers on porous media...
