Abstract

Wire woven metals are new type of truss-like periodic cellular metals (PCM) that have several applications ranging from different loading applications to filtering processes. Their lightness, decent structural integrity and other thermo-fluid mechanics have resulted in a multi-functional structure. Wire bulk cross (WBC), that represents the 3D model of wire woven screens, recently recognised as the premier truss-like PCM in terms of normalized compressive and shear strength. In addition, it shows decent resistance to buckling effects. Homogeneity of these structures can also provide a uniform flow with minimal pressure drop and velocity perturbation in industries that maintaining design and operating conditions of flow is critical. In Oil & Gas industry, packing towers imply an essential requirement that operating conditions of vapor flows should remain unchanged, while heavy random packings, mounted on the top, are well-supported. Thus, investigation on effects of wire woven mesh screen aperture size on its structural integrity, while minimising flow pressure-drop and velocity profile changes can introduce these truss-like structures as tower packing supports. In this research, using FEA, wire woven mesh screens undergo several aperture sizes to investigate the mechanical behaviour of the structure. Similarly, CFD analysis conducted to simulate the behaviour of vapor flows through these wire woven mesh screens. The numerical results are then plotted against both porosity ratio and aperture size to indicate the mechanical and flow behaviour patterns. In the CFD analysis graphs, flooding point of the nominated nitrogen flow is shown to give an inside into the points when flow might entre flooded region. Results showed deflection of the mesh under the load, fluid velocity profile and pressure drop values level off after certain sizes are reached. Normalized combination of these analysis can then be used to optimise and determine acceptable aperture size ranges that meet the requirements in specific industry applications.
