In present study, a three-step multi-objective optimization algorithm of cyclone separators is catered for the design objectives. First, the pressure drop (Dp) and collection efficiency (h) in a set of cyclone separators are numerically evaluated. Secondly, two meta models based on the evolved Group Method of Data Handling (GMDH) type neural networks are regarded to model the Dp and h as the required functions of geometrical characteristics. Finally, a multi-objective (MO) algorithm based on hybrid of Particle Swarm Optimization (PSO), multiple crossover and mutation operator are used for Pareto based optimization of cyclones considering two conflicting objectives Dp and h. By comparing the Pareto results of MOPSO with that of multi-objective genetic algorithms (NSGA II) regarding Pareto based multi-objective optimization of the obtained polynomial meta-models, it is shown that there are some interesting and important relationships as useful optimal design principles involved in the performance of cyclone separators.
