Solidification of Impinging Molten Metal Droplet on a Cold Substrate
The phenomenon of impingement and solidification of a molten metal droplet on a substrate occurs in processes like thermal spray coating and spray casting. Molten metal droplet after impingement over a substrate becomes a splat after spreading and solidification. The phenomenon of spreading and solidification of a droplet can be understood by mathematical modeling. In the present work, the spre...
متن کاملModeling Of Heat Transfer And Solidification Of Droplet/Substrate In Microcasting SDM Process
Microcasting Shape-Deposition-Manufacturing is an approach to Solid-Freeform-Fabrication (SFF) process which is a novel method for rapid automated manufacturing of near-net-shape multi-material parts with complex geometries. By this method, objects are made by sequentially depositing molten metal droplets on a substrate and shaping by a CNC tool, layer by layer. Important issues are concerned w...
متن کاملEulerian-lagrangian Modelling with Stochastic Approach for Droplet-droplet Collisions
In recent years, there has been growing interest to use computational fluid dynamics (CFD) for exploring dropletparticles interaction under the turbulent flow of air inside spray dryer systems. The final goal is to predict the dried solid particle size and mass flux distributions under the conditions of collision, coalescence and agglomeration of the droplets and particles. The coarse-grained s...

متن کاملEvolution of solidification texture during additive manufacturing.
Striking differences in the solidification textures of a nickel based alloy owing to changes in laser scanning pattern during additive manufacturing are examined based on theory and experimental data. Understanding and controlling texture are important because it affects mechanical and chemical properties. Solidification texture depends on the local heat flow directions and competitive grain gr...
