Strategic Objectives
• Master the physics of surface tension-driven flow and Marangoni convection.
• Identify the root causes of pore entrapment and gas porosity in liquid metal.
• Optimize heat transfer models to predict melt pool geometry with precision.
• Control transient turbulence to eliminate internal structural inconsistencies.
The Core Challenge
Traditional manufacturing overlooks the chaotic fluid dynamics of the melt pool, leading to unpredictable internal defects and structural failure.
