CHALLENGE - Geometric optimization of a cyclone separator usually employed for filtering natural gas before being supplied through pipes to homes. This study focuses on the design of this device for natural gas. The goal is minimization of the pressure drop through the cyclone separator for an assigned collection efficiency.

SOLUTION - An optimization process using 3D CFD simulations and the genetic algorithm MOGA-II available in modeFRONTIER was utilized to minimize the pressure drop of the cyclone separator without reducing the centrifugal force. CFD results show a 1.8% difference between experimental pressure drop and numerical prediction. 

BENEFITS - The method using modeFRONTIER results in the optimized geometry producing a pressure drop reduction of about 20%. Upcoming works will account for simulation of the particles and the collection efficiency will be evaluated by calculating the number of the separated particles.
