The Efficiency Coefficient of a Separator with Mesh Orifices

As Wo gets lower, the critical velocity increases. This means that string orifices can be used with the greatest efficiency in the separation of gas with a low concentration of liquid. Note that usually the condensate factor is given assuming the normal conditions, while in the calculation formulas presented above, W is taken at the operating conditions. This fact should be kept in mind when comparing theoretical results vdth experimental ones. 

The Efficiency Coefficient of a Separator with Mesh Orifices 

Mesh droplet catcher orifices are made from hose knitted grid and placed in vertical and horizontal separators in the device cross-section. 

Deposition of drops on grid wires is similar to deposition of drops on strings, which was considered in the previous section. As opposed to string orifices, the internal structure of mesh orifices is characterized by a chaotic distribution of cells over the orifice thickness. A mesh orifice can be considered as a porous highly permeable medium with the following intrinsic parameters specific free volume v (m /m ) thickness of the mesh bundle H average size of grid cells I X 1 diameter of wires d.  

A mesh bundle will be modeled by N parallel flat layers of grid, with a constant distance h between them. Specific volume may be expressed in terms of the geometrical parameters of the grid
