On Quantitative Estimation of Laser Melting Phenomenon with Numerical Visualization Technique

Numerical model based reliability estimation of selective laser melting process

Selective laser melting is developing into a standard manufacturing technology with applications in various sectors. However, the process is still far from being at par with conventional processes such as welding and casting, the primary reason of which is the unreliability of the process. While various numerical modelling and experimental studies are being carried out to better understand and ...

Numerical Simulation Of Heat Affected Zone Microstructure During Laser Surface Melting

Microstructural changes during laser welding and laser surface treatment has been regarded by many researchers. Most researches have focused on studying the effect of various process parameters on the size and microstructure of the heat affected zone. But some studies show that the initial microstructure of the base metal can also affect the heat affected zone dimensions and final microstructur...

Influence of Internal Topologies on Components Produced by Selective Laser Melting: Numerical Analysis

Regardless of the manufacturing process used, subtractive or additive, material, purpose and application, produced components are conventionally solid mass with more or less complex shape depending on the production technology selected. Aspects such as reducing the weight of components, associated with the low volume of material required and the almost non-existent material waste, speed and fle...

Numerical Model of Melting Problems

In the present study, a finite volume method is employed to model the advection-diffusion phenomenon during a pure substance melting process. The exercise is limited to a benchmark problem consisting of the 2D melting from a vertical wall of a PCM driven by natural convection in the melt. Numerical results, mainly the temporal evolution of average Nusselt number at the hot wall and the average ...
