..., segregation, stress concentration, etc., seriously reduce the properties and strength of the joint or solidification. Even though different mechanisms for formation of the defects have been extensively proposed in the past, more systematical understanding of pattern formations from thermal, fluid, physics...

... evaluation of carbon load performed at the end of a single test. The explanation can be found in the tendency for char particles to float and segregate near bed surface 14 , where bed sampling is performed. Figure 3 reports a temperature profile along the combustor axis at different fluidization...
