Numerical and scale modeling studies of Vortecone, a pressure-driven wet-scrubber device for the efficient capture of over-sprayed paint in the automobile industry, are presented. In this manuscript, Vortecone was tested for removing dust particles from underground mining operations. The pressures required to operate Vortecone and the airflow rates through the Vortecone are the two most important factors for mine ventilation systems. This study used dry, no-particle conditions to obtain relationship between these two parameters and then designed a Vortecone filter ventilation system for mining operations. Commercial software, SC/Flow, was used to generate the CFD model with unstructured meshes and a series of numerical calculations were accomplished. Included in these were calculation of a 1/3rd scale model of Vortecone along with experimentation that was accomplished to validate the numerical predictions. The experiments were conducted to measure pressure drops for known airflow velocities at critical points within Vortecone. The scale model experimental results agreed very well with the CFD numerical calculations. For scaling the performance of the 1/3rd scale model to full scale, the scaling laws were developed using the law approach; they are discussed along with the feasibility of the Vortecone filter system for underground mining operations.
