COMSOL software using appropriate boundary conditions was used for rapid analysis of flow through the system. To calibrate the theoretical results velocity, pressure and flow rates were measured on the actual full-scale unit. These tests were carried out using pitot tube, digital manometer and special duct flow measurer. Experimental result was compared with the obtained simulation result. The effect of duct geometry on the velocity distribution through the grate was established through this exercise.enThe copyright for the paper content remains with the author.Fluid MechanicsArticle
