Cost-effective 3D H-filter fabricated by xurographic method

In this paper, the conventional 2D H-filter is modified to 3D multi-layer structures fabricated by low-cost xurography. The extraction efficiency was studied experimentally for different 3D structures and then compared with conventional 2D H-filter. Numerical simulations were performed to model the diffusion flow in the proposed H-filters, showing a good agreement with the experimental observations. Results show that 3D H-filters have higher extraction efficiency at the same Reynolds number. Moreover, these structures could benefit low-cost and commercial applications due to their higher efficiency at smaller sizes.
