| Popis: | The Rayleigh–Benard 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–Benard convection effect plays a vital role in getting smooth continuos track in laser melting process. The Rayleigh–Benard convection enhances the heat transfer phenomena throughout the powder bed. The type of Rayleigh–Benard convection flow identified during simulation is source flow. Rayleigh–Benard 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–Benard convection flow in laser melting process. |
