Design and calculation of cylindrical industrial air filter device with use of CFD analysis

In order to reduce emissions and improve the quality of ambient air or air in the working space it is necessary to clean emission particles. Air purity is achieved by proper filtration process of emission particles. In this paper housing of cylindrical industrial air filter device was designed and optimized with the use of CFD analysis. Model of cylindrical filter device was made in the software SolidWorks Premium 2016. Several models of product were made until satisfactory design from the perspective of functional and technological feasibility was reached. Furthermore, multi physical analysis was conducted in software ANSYS Workbench. CFD analysis of fluid flow was carried out using software ANSYS CFX. Based on CFD analysis of fluid flow and distribution of pressure on filter device wall, analysis of strength was conducted in ANSYS Static Structural, and model optimization in ANSYS DesignXplorer. Optimized model serves as an orientation model for further analysis of critical loads (underpressure, overpressure). Optimized model strength analysis at working pressure with value of -1277.6 Pa show that maximum equivalent stress is 114.03 MPa. In the condition of high value of overpressure with value of 1059.43 Pa maximum equivalent stress is 378.09 MPa, and for high value of underpressure with value of -5936.6 Pa maximum equivalent stress is 534.91 MPa. Optimized model requires further work in order to reduce stresses in the case of critical loads. This paper presents a coupling of CAD and CAE technologies in process of new product development.
