BackgroundThe thermal diffusivity and vertical seepage velocity of porous media are critical to characterizing the mechanisms underlying subsurface heat transfer. These two parameters are typically determined through inv...

This study aims to systematically analyze the new characteristics, evolution trends, and causes of major extreme weather in China in the context of global climate change, and evaluate the current forecasting, early-warni...

For the molten pool behavior in K-TIG welding, the Level-Set method was used to track the changes in the free surface of the molten pool, and a two-dimensional transient numerical calculation model for stationary welding...

Abstract: To investigate the interaction of heterogeneous solutes in the common molten pool flow during laser welding of heat-resistant steel and nickel-based alloy, a multiphase flow coupled welding model was establishe...
