A Pressure Drop Model for Spacer Grids with and without Flow Mixing Vanes

In summary, the proposed model showed the reasonably accurate predictions for various grids investigated here. It yields also better predictions than others do. Even some improvements are needed in the model, however, it is concluded that the proposed model for pressure drop can provide sufficiently...

Zusammenfassung:	In summary, the proposed model showed the reasonably accurate predictions for various grids investigated here. It yields also better predictions than others do. Even some improvements are needed in the model, however, it is concluded that the proposed model for pressure drop can provide sufficiently good approximation for grid optimization and design calculation in advanced grid development.
