Missing interface level

Drop settles and coalesces but is re-entrained] faulty location of exit nozzles for liquid phases/distance between exit nozzle and interface is < 0.2 m/overflow baffle corroded and faUure/interface level at the wrong location/faulty control of interface/liquid exit velocities too high/vortex breaker missing or faulty on underflow line/no syphon break on underflow line/liquid exit velocities too high. [Drop settles but doesn t coalesce [phase inversion] /pH far from zpc/surfactants, particulates or polymers present/electrolyte concentration in the continuous phase < expected/[coalescer pads ineffective] /[drop size decrease] /[secondary haze forms] /[stable emulsion formation] /[interfacial tension too low] /[Maran-goni effect]. ...

The most extensive approach to the investigation of fuel cells numerically so far, applies continuum equations and global relations to predict the characteristics of fuel cells on a system level. For porous material, the homogeneous properties of porous material, like porosity and tortuosity, are used to calculate an equivalent result. This strategy reduces the complexity of modelling within the microstructure but sacrifices the precision of modeling. Moreover, detailed information of the transfer process at the electrode/electrotyte interface is missing.
