Experimental and numerical investigation of dry pressure drop of 3D-printed structured packings for gas/liquid contactors

• Dry pressure drop for two types of complex structured packing is evaluated experimentally and numerically. A numerical model established validated with an average deviation ≤ 20% from the experimental data. The advantages/drawbacks results different computational domains dry study are presented. a wire-based column 16,500 cm 3 produced using periodic rectangular domain 42 . effect penalty on gas distribution around structure discussed. Separation units, such as distillation absorption columns, used widely in chemical industry. Their efficiency depends performance their packing, determined by drop, capacity, mass transfer efficiency. Combining CFD additive manufacturing allows design/production efficient high capacity packing. In this paper, drops newly developed packings numerically via single-phase model. k -ω-SST turbulence Ansys Fluent was used. three Tetraspline (TS) compared. errors 13% compared data TS made stainless steel polyamide, respectively, over factor range 0.9 to 3.1 Pa 0.5 Kelvin-cell-based also studied confirm robustness This rapid optimisation geometric parameters, wire diameter length, based drop. Indeed, values that measures have been reproduced only small
