This study is part of a multi-disciplinary research effort to better understand, document and optimize the operation of Rimer Alco North America’s Refuge One for the global mining industry. In this thesis, an experimental and numerical study of turbulent flow inside a Refuge One is undertaken to understand the flow characteristics through a Refuge One hopper, compare the predictive performance of five different turbulence models and optimize the flow through the Refuge One hopper to enhance its performance. The experimental study is performed using a particle image velocimetry technique for two Reynolds numbers 53,000 and 23,000, respectively. The numerical study is performed by solving the Reynolds-Averaged Navier-Stokes equations together with k-ε, RNG k-ε, k-ω, k-ω based SST and Reynolds stress turbulence models using the commercial CFD code CFX 15.0. Flow optimization is performed for hoppers by choosing different hopper height and wall shape configurations and their performances are evaluated. / October 2016
