| Abstract: | In this work, a ray tracing model has been introduced which simulates the light absorption in 2D and 3D particle beds. A finite number of rays, representing a laser beam, propagate into a particle bed, causing the particles to absorb the light and increase in temperature. A simplification has been proposed which replaces these ray tracing simulations, making it a computationally friendly method of computing the absorption while being able to change several variables. These simplifications have been done for a particle doublet and a particle bed in the form of a set of equations, and the use of a semi-random walk was investigated. The equations can subsequently be used in simulations of powder bed sintering. |
