Sharp optimization of hydrocyclone based on Fluent mesh morphing
摘要
Abstract
Currently,fluid-structure optimization of hydrocyclone has been mainly limited to single-parameter size optimization. Generally,the optimization process is dependent upon the method of separate simulation with multiple sets of grid. Nevertheless,the approach is time-consuming and not capable of controlling the micro size deformation. Besides,further improvement on the separation efficiency of cyclone is rather difficult once a certain maximum optimization is achieved. To solve this problem,mesh deformation-based shape optimization method was proposed. Aimed at improving the hydrocyclone separation efficiency with ANSYS Fluent mesh deformation method,the hydrocyclone sharp structure was optimized and the hydrocyclone separation efficiency was increased from 95.69% to 99.18%. A comparative analysis involved with pressure drop,velocity and oil phase volume distributions before and after optimization was then conducted. The results indicated that the smoothing mesh deformation driven grid nodes by Fluent mesh morpher could concurrently contribute to the optimal combination of structural parameters in the deformation zone,and the optimization of the automation and intelligentization of the iteration process. Besides,it had a considerable capability of global searching and strong robustness. Fluent mesh morphing optimization algorithm can shorten CAD modeling time,avoid mesh reconstruction and further improve the separation efficiency of hydrocyclone within a certain range on the basis of single-parameter size optimization.关键词
