In the cold fusion experiment, there observed
vortex patterns on a thick Pd rod electrode surface during
long-term electrolysis in 0.1M LiOD. To understand the
peculiar phenomenon, we had proposed N-cycle model,
which is composed of four sequential processes including the
CF reaction. In this study, numerical simulation for the
analysis of the vortex patterns was performed to elucidate
the relation between the vortex formation and the CF
reaction. Supposing that the hypothetical particles mass
evolved due to the CF reaction energy, we performed the
numerical simulation using discretization method for the
analysis of 3D motion of the hypothetical particles mass.
The experimental results showed that the ejected particles
mass from one side to another in a given rectangular box
(simulate the sub-surface layer) exhibited a helical
trajectory as a function of magnetic field. The traces of the
ejected particles mass on another side composed vortex
pattern. There has been remained more accurate simulation
to examine the structure of the layer and the influence of the
magnetic field.
