Abstract In this paper, a numerical study is performed to investigate the effects of thermal shrinkage on the deposition of molten particles on a substrate in a
thermal spray process using the Volume-of-Fluid (VOF) method. Thermal shrinkage is a phenomenon caused by the variation of density during
cooling and solidification of a molten metal. The Navier-Stokes equations along with the energy equation including phase change are solved using a
2D/axisymmetric mesh. The VOF method is used to track the free surface of molten particles, and an enthalpy-porosity formulation is used to model
solidification. For the normal impact of tin particles in… More >
