Abstract: A paint removal booth assembly includes a paint removal booth that defines an interior and includes an entry door for allowing a skid having built-up paint overspray to enter the interior. A platform is disposed within the interior of the paint removal booth adjacent to the entry door for receiving the skid. At least one laser ablation device is disposed in the interior of the paint removal booth and configured to generate and direct a laser beam towards the skid for ablating the built-up paint overspray from the skid and generating ablated paint particles in the interior of the paint removal booth. A debris capturing assembly is disposed in fluid communication with interior of the paint removal booth for drawing the ablated paint particles from the interior of the paint removal booth and directing them to a collection drum disposed in an environment outside of the paint removal booth.

Abstract: A method for tracking N fluid materials and their associated interfaces during simulated fluid flow is disclosed. A microgrid cell methodology is embedded on a regular macrogrid to subdivide and then tag fluid materials in a computational system preferably using a prime numbering algorithm. The motion of microgrid cells is tracked based on local velocity conditions, rectifying small anomalies by a coupled evaluation of local volume fraction fields and global mass conservation. Volume fractions can be calculated at any time step via an evaluation of the prime locations so that average cellular density and viscosity values can be regularly updated.
