The formation and evolution of vapor channels in a liquid-saturated and heatgenerating particulate bed is modeled. The effect of the sticking forces on the onset of channeling is considered. Simple experimental techniques are devised to support the model development. Satisfactory interpretation of the D10 in-pile test performed at Sandia Laboratories can be achieved with the present channel model.
