Numerical Study of Molten Metal Melt Pool Behaviour during Conduction-mode Laser Spot Melting
Amin Ebrahimi, Chris R. Kleijn, Ian M. Richardson
Molten metal melt pools are characterised by highly non-linear responses, which are very sensitive to imposed boundary conditions. Temporal and spatial variations in the energy flu…
The influence of surface deformation on thermocapillary flow instabilities in low Prandtl melting pools with surfactants
Amin Ebrahimi, Chris R. Kleijn, Ian M. Richardson
Heat and fluid flow in low Prandtl number melting pools during laser processing of materials are sensitive to the prescribed boundary conditions, and the responses are highly nonli…
Sensitivity of Numerical Predictions to the Permeability Coefficient in Simulations of Melting and Solidification Using the Enthalpy-Porosity Method
Amin Ebrahimi, Chris R. Kleijn, Ian M. Richardson
The high degree of uncertainty and conflicting literature data on the value of the permeability coefficient (also known as the mushy zone constant), which aims to dampen fluid velo…
