Forms of droplets held on a wire mesh (type: mist eliminator) was observed by solidification of melting paraffin wax under conditions of stationary air and by a borescope in air flow.Droplets were held in the valley part of the waved mesh in the stationary and low velocity regions. When the flow velocity exceeds the loading point, the diameter of droplets increases remarkably. Droplets were carried away from the mesh at the flooding point, and the diameter increased with increase in the flow velocity.A balance equation of forces acting on a droplet could explain the observed data. The estimated radius of meniscus between a droplet and a wire of the mesh was calculated to evaluate adhesive forces other than gravity and drag.
