Numerical modeling of heat transfer during hydrogen absorption in thin double-layered annular ZrCo beds

Numerical modeling of heat transfer during hydrogen absorption in thin double-layered annular ZrCo beds

In this work a three-dimensional (3D) hydrogen absorption model was proposed to study the heat transfer behavior in thin double-layered annular ZrCo beds. Numerical simulations were performed to investigate the effects of conversion layer thickness, thermal conductivity, cooling medium and its flow...
