Flow of non-spherical particles in laser sintering
Understanding the flow of non-spherical particles is essential in several industrial processes such as laser sintering. In the first stage of this process a polymeric powder is spread to form a powder bed. Commercially available polymer powders are generally considered as spherical particles for design and prediction purposes, however still, subtle variation in particle morphology is present. Flow of non-spherical particles and shape effects are not adequately understood compared to the spherical particles, which results in unpredictability of properties of final product and inefficient design. Investigation of shape effects on flow of non-spherical particles is one of the major objectives of this project which will be achieved using state of the art discrete element (DEM) simulations.
