Abstract
The Rayleigh–Bénard is also known as Gibbs–Marangoni effect. In this effect the mass transfer occurs along an interface between liquid and air due to its surface tension gradient. Rayleigh–Bénard convection effect plays a vital role in getting smooth continuos track in laser melting process. The Rayleigh–Bénard convection enhances the heat transfer phenomena throughout the powder bed. The type of Rayleigh–Bénard convection flow identified during simulation is source flow. Rayleigh–Bénard convection flow which shows the pattern of clockwise flow is defined as source flow. Overall convection flow found in this studies are of clockwise flow. This study mainly focuses its attention on the effect of Rayleigh–Bénard convection flow in laser melting process.
