Monte Carlo Prediction Of Non-Newtonian Viscous Sintering: Experimental Validation For The Two-Glass-Cylinder System

From the Monte Carlo methodology based on a non-discrete potential and developed to model capillary-driven mass transport, a relation between the Monte Carlo step and the physical time has been defined as a function of the viscosity coefficient. The experimental kinetics of the shortening of a unique glass cylinder and the sintering of two-glass cylinders at 950 deg C then have been compared with the numerically obtained results. The original result indicates that the active sintering mechanism for a glass under the given sintering conditions is not Newtonian viscous flow alone, a finding that corresponds perfectly well with the Monte Carlo simulation.
