Metallic screens have important functions in tank systems and feedline systems of spacecraft’s due to their filtering capabilities and capillary features. The screen resistance upon flow through is significant influenced by the individual mesh and pore geometry of the individual screen. In this paper the screens are numerical investigated by using the commercial solver ANSYS Fluent 13.0. Calculations for low to medium screen Reynolds numbers with the different fluids water, liquid hydrogen and IPA are carried out. The results show good agreement with experimental and analytical data. Furthermore the streamlines, the local velocity and pressure field are investigated
