Abstract: In order to better guide the cyclone design and optimization, the theoretical basis, applicability and accuracy of the prediction models of cyclone performance were investigated. Research progress on the prediction models of separation performance and pressure drop was reviewed. Combined with the influence of the particle load, particle size distribution, particle collision and coalescence, high temperature, high pressure, structure and parameters on the separation performance, the prediction models were compared and analyzed from aspects of the theoretical basis, modeling ideas and modeling tools. The results showed that prediction models were gradually rationalized but still limited. Based on the current conditions of research and application, the future direction for development of the prediction models was prospected. Comprehensive analysis of various factors' effects on the prediction models and the extension of the gassolid separation theory and prediction models to the gas-liquid separation field might be the focus of the further research．
