RISDynamic Performance Characteristics of a Porous Volumetric Solar Receiver Under Transient Flux Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The solar flux incident on a volumetric receiver is inherently unsteady, resulting in high thermal stresses, fatigue failures, and reduced component life. The knowledge of transient response characteristics of a porous ...
Pore Scale Numerical Investigation of Mixed Convection From an Isolated Heat Source in a Channel With a Porous Insert
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Mixed convection heat transfer in a channel filled with porous medium and containing an isolated heat source at the bottom wall is studied in this work. The porous medium is assumed to be made of circular cylinders and is ...
