Title: The effects of laser characteristics on melting of nano-particles on a surface


Biography: Peng-Sheng Wei


This study numerically investigates transport processes during the melting of an array of nanoparticles on a surface subject to an electromagnetic wave or laser beam in a transverse magnetic (TM) mode. The TM mode represents magnetic field to be perpendicular to the incident plane of electrical field. A systematical investigation of heating and melting of an array of nanoparticles on a surface is essentially required to understand 3-D printing and different types of plasma processing and nanotechnology. The results show that electromagnetic wave propagating along the boundary between two media leads to a distributed heat input and magnetic force on the surface. Fluid flow and heat transfer associated with surface deformation result in complicated transport phenomena between nanoparticles, especially for different frequencies and radii of incident electromagnetic wave.
