Modelling of dendritic growth during alloy solidification under natural convection

A two-dimensional (2D) lattice Boltzmann method (LBM)-cellular automaton model is presented to investigate the dendritic growth of binary alloys in the presence of natural convection. The kinetic-based LBM is adopted to calculate the transport phenomena by the evolution of distribution functions of moving pseudo-particles. To numerically solve natural convection thermal and solute transport sim...

Rapid Solidification of Polymeric Fibers

A thorough understanding of crystallization kinetics for rapid polymer solidification during the fiber spinning process is a route to maximizing fiber properties while increasing production speeds. We are using theoretical, computational, and experimental models to characterize the crystallization process at the molecular, microscopic, and macroscopic levels. Polymer dependent molecular descrip...

Initiation and growth kinetics of solidification cracking during welding of steel

Solidification cracking is a key phenomenon associated with defect formation during welding. To elucidate the failure mechanisms, solidification cracking during arc welding of steel are investigated in situ with high-speed, high-energy synchrotron X-ray radiography. Damage initiates at relatively low true strain of about 3.1% in the form of micro-cavities at the weld subsurface where peak volum...
