Investigations on dynamic water transport characteristics in flow field channels using neutron imaging techniques

► Three basic flow field designs are investigated: pattern structure, meander-shaped channels, straight channels. ► Flow fields are compared regarding power and water inventory. ► Water thicknesses under channel and under land are separately calculated. ► Results of neutron radiography and CFD simulation are combined. ► A condensate removal criterion of 20 mbar m−1 is proven.
