Abstract:Two particle filters were designed using a vortex trap concept with equally spaced channels and tortuous airflow paths. A small wind tunnel was built to evaluate the filters’ efficiency under various conditions. Emphasis is placed on the effect of the following parameters, namely, tortuosity, T = 1.3 and 2.0, square conduit size of 0.4 mm and 0.7 mm, and incoming flow velocity U =0.2 m/s and 0.4 m/s. Results show that a particle size on the order of 10 μm passing through a two-layer filter with T = 2 and square-hole size of 0.7 mm width provide 98.5% efficiency.
