A computational and experimental study of fluid flow in a de-duster

Abstract

A three-dimensional computational fluid dynamics model with an RNG k-ε model and second upwind scheme in the Fluent package was used to simulate the flowpattern in a de-duster. The model predictions for the flow field inside the dispersion device were compared with LDA measurements. The primary objectives are to understand such complex flow fields and to guide the development and optimisation of this de-duster. From the simulation results, the old prototype appears to have some disadvantages and shortcomings. A modification is proposed here to overcome some of these. The major new development in modification is the introduction of a second air inlet and the optimisation of the de-duster geometry. The modification will minimize the disadvantages and shortcomings identified so far.
