RISDirect Numerical Simulation and RANS Comparison of Turbulent Convective Heat Transfer in a Staggered Ribbed Channel With High Blockage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A turbulent convective flow of an incompressible fluid inside a staggered ribbed channel with high blockage at ReH ≈ 4200 is simulated with direct numerical simulation (DNS) and Reynolds-averaged Navier–Stokes (RANS) ...
Large Eddy Simulation of Liquid Metal Turbulent Mixed Convection in a Vertical Concentric Annulus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present study, turbulent forced and mixed convection heat transfer to a liquid metal flowing upwards in a concentric annulus is numerically investigated by means of large eddy simulation (LES). The inner-to-outer ...
Entropy Generation Minimization Analysis of Solar Salt, Sodium, and Lead–Bismuth Eutectic as High Temperature Heat Transfer Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The amount of entropy generation in heat transfer devices impacts their operation economy and should therefore be minimized during the design phase. Entropy generation also depends on the individual thermophysical properties ...
