Pulsating turbulent flow fields and heat transfer characteristics in pipes for automotive engine exhaust systems.
It was found that turbulence in the flow field and the time variation of secondary flow and vortex structure at the bend, which occurs only in curved pipes, affect wall heat transfer, leading to heat transfer suppression and heat loss reduction in curved pipes.
Development of Hot-wire Laser AM Technology for Stainless steel / Aluminum Alloy Dissimilar Materials
The hot-wire laser AM technology being researched and developed combines the hot-wire method with a high-power diode laser to enable precise heat input control and a significant reduction in heat input to the substrate material, as well as ultra-high efficiency production.
Development and characterization of sheet-based thermal interface materials using carbon nanofibers
A high performance thermal interface sheet with excellent thermal resistance and thermal conductivity was developed.
