       abstract = "Predictive pressure drop models have been identified for membrane channels with
         both woven and non-woven spacers as found in plate and frame or spiral wound membrane modules. The
         models allow for the first time the thorough quantitative description of the pressure drop for a
         wide range of design parameters specifying the thickness and orientation of the spacer filaments. A
         systematic work flow has been developed efficiently integrating detailed computational fluid
         dynamics (CFD) simulations on high-performance computing (HPC) systems with established
         optimization-based model identification methods. The work-flow efficiently handles the complexity
         arising from the large number of design parameters and allows for the model identification with
         minimal number of \{CFD\} simulations. The resulting models facilitate for the first time
         a thorough sensitivity analysis of the pressure drop with respect to all important design parameters
         elucidating strongly nonlinear patterns in the sensitivities. This indicates that the generalization
         of trends from a small number of \{CFD\} simulations, frequently used in previous work to
         simplify the spacer design problem, can yield inaccurate results.",
