Investigation of the melt movement along the fuel pin surface during accidents

Investigation of the melt movement along the fuel pin surface during accidents Methods for calculating the motion of a melt along the fuel element surface under the conditions of an accident are presented. The calculation was carried out using semianalytic methods for the shear stress and gravity-driven films. The results of calculations of the motion of a melt under various initial conditions are presented. Particular attention is paid to the influence of surface tension forces on the interface between the melt and a solid surface. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Methods for calculating the motion of a melt along the fuel element surface under the conditions of an accident are presented. The calculation was carried out using semianalytic methods for the shear stress and gravity-driven films. The results of calculations of the motion of a melt under various initial conditions are presented. Particular attention is paid to the influence of surface tension forces on the interface between the melt and a solid surface.
