Abstract

Method of designing and manufacturing a distributor bar for use in a production line comprising a mixing head for providing a viscous foamable liquid mixture, a laminator with a predefined speed of at least 20 m/min, the distributor bar having a central inlet fluidly connected to a number of outlets via a main channel. The method comprises: choosing () a geometry for the distributor bar and defining a set of geometrical parameters; assigning () values to said parameters; creating () a virtual model; simulating () flow in said model by performing a Computational Fluid Dynamics simulation (CFD), taking into account () a non-Newtonian shear thinning model; e) evaluating the simulated flow; building () a physical distributor bar. A distributor bar, a production line, and a computer program product.
