Abstract

Filtration is not only applied in domestic used, it also being applied in industry widely. However, the industry facing few challenges when pressure and velocity of the fluid are unstable and inconsistent throughout the pipeline especially during fluid passes through the filter , causing high power consumption to provide higher pressure. Thus, affect the performance of the filter, as well as require more manpower for maintenance, higher cost, and delay the production. Therefore, more effective filter is required and the designing of the better structure is one of the most crucial parts. A new approach to be implemented is by using non-stochastic lattice structure as the porous media. Hence, this study will focus on the performance of the non-stochastic lattice structure in filters media as the filter mesh. The performances observed are include velocity, flow characteristics, and pressure drop at the outlet of the filter. These observations were carried out on three different structures, hexagon, rhombic dodecahedron, and kagome using SolidWorks Flow Simulation software at five different inlet velocity (1 mis, 3 mis, 6 mis, 9 mis , and 12 mis). The results obtained are compared among the three lattice structure and find out that Rhombic Dodecahedron lattice has the minimum pressure drop. Finite Element Analysis (FEA) is also in vestigated to observe the mechanical properties of the structure such as Von Mises stress, strain, and its Factor of Safety. From the analysis, it is shown that hexagon has highest Factor of Safety even though at increasing inlet velocity
