Comparison Study of Three or Two Dimensional Analytical Model for Simulation of Thermal Conductivity in Thermally Sprayed Ceramic Coatings Available to Purchase

This study compares the accuracy of 2D and 3D models for determining the thermal conductivity of thermally sprayed ceramic coatings. Although the overall dependency of relative thermal resistance on microstructural parameters is similar for the two models, the detailed dependency is quite different and is more accurate in the 2D model. With increasing unit size and decreasing splat thickness and bonding ratio, the 2D model is more effective than the 3D model due to its more appropriate assumption of splat thickness relative to the distance between cracks.
