Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>The aim of this work is to design a cyclone separator, which could reach the highest separation efficiency for fine and low‐density particles (1–10 µm) and air‐flow rates between 10 and 100 L/min. The first part of the study is dedicated to the design, thanks to <sc>cyclone</sc> software developed by PROGEPI, Nancy, France. It uses classical models and does not take into account the dispersed phase fraction, but allows giving a first approach of the cyclone geometry. Results lead to a Lorenz geometry and pressure drop lower than 10 KPa for 100 L/min. The separation efficiency is never lower than 75% for 2‐µm particles at 50 L/min. In the second part, a computational fluid dynamics study via <sc>flue</sc><sc>nt</sc> is conducted in order to determine the performances of the device, thanks to the particle trajectories simulations. Results show that for the higher flow rate (100 L/min), a separation efficiency of 60% is reached for 1‐µm particles. For a lower flow rate (10 L/min), this cyclone is not satisfying because no 1‐µm particles are separated. This study shows that these two approaches are quite complementary in order to reach the most accurate design.
