11 - Numerical Analysis of Flow Properties in the Collection Chamber

Abstract

This chapter presents the numerical analysis of flow properties in the collection chamber. Mineral wool primary layer formation is influenced by the aerodynamic characteristics of the blow away flow and the secondary, surrounding air flow. The computer-aided visualization method was used for quantitative description of the uniformity of the primary layer. Images were acquired using the black-and-white Charge-Coupled Devices (CCD) camera. The distribution of mineral wool perpendicular to the primary layer movement is estimated by using the time-averaged local mass of the primary layer. The chapter presents a simple numerical model of air flow aerodynamic characteristics in the collection chamber. To investigate the dependence of the primary layer structure on the air flow velocity field inside the collection chamber, a study of the distribution of the primary layer structure at selected longitudinal regions on the perforated mesh is necessary.
