Research Article | The removal of unwanted droplets in thermal separation units is often accomplished using knitted wire meshes. Alongside the separation efficiency, the pressure drop plays a crucial role for the design of these demisters. Based on experimental analyses of porosity and dry pressure drop over a wide range of wire mesh parameters and intake gas velocities as well as further data from the literature, an empirical correlation was developed. It enables prediction of the pressure drop with a mean deviation of ±20 %.
