The study of flow and heat transfer through porous media or randomly packed beds is important as these configurations are widely used in many engineering applications, for example, energy storage, chemical catalytic reactors, nuclear reactors. mixing characteristics a cross-flow plane facility with spheres at an aspect ratio 6.3 were experimentally investigated. velocity fields several regions the located vicinity wall pores between obtained by applying matched-index-of-refraction...
Abstract The thermal-hydraulic behavior of the flow in rod bundles has motivated numerous experimental and computational investigations. Previous studies have identified potential for accumulation debris within small subchannels typical wire-wrapped assemblies with subsequent total or partial blockage subchannel coolant flow. A test campaign was conducted to study effects localized blockages on bundle averaged friction factor a tightly packed bundle. Blockages were installed bundle, fluid...
Abstract This work experimentally investigated the flow phenomena and vortex structures in wake of a sphere located water loop at Reynolds numbers Re = 850, 1,250, 1,700. Velocity fields region were obtained by applying time-resolved stereoscopic particle image velocimetry (TR-SPIV) technique. From acquired TR-SPIV velocity vector fields, statistical values mean fluctuating velocities computed. Spectral analysis, two-point velocity–velocity cross-correlation, proper orthogonal decomposition...
The verification and validation of Pronghorn is imperative for predicting the fluid velocity, pressure, temperature in advanced reactors, specifically high-temperature gas-cooled reactors. a coarse-mesh, intermediate-fidelity, multidimensional thermal-hydraulic code developed by Idaho National Laboratory. incompressible Navier-Stokes equations are validated using pressure drop measurements axial velocity averaged from particle image velocimetry data obtained at engineering-scale pebble bed...
This research work seeks to investigate the influence of spacing and heat transfer on wake behavior a triangular arrangement spheres. Four experimental configurations have been investigated at three Reynolds numbers, Re1 = 350, Re2 700, Re3 1050. Two isothermal cases were with between spheres zero one sphere diameter, two an applied flux same conditions. The time resolved particle image velocimetry results revealed various flow phenomena including separations, von Karman vortex shedding,...
Complex geometries and randomly connected void spaces within packed beds have hindered efforts to characterize the underlying transport phenomena occurring within. In this communication, we present our experimental studies on a facility of spheres that can be representative sections reactor core in nuclear power plant.
