Experimental investigation into laboratory effects of an OWC wave energy converter

Reproducibility advances science and de-risks engineering. In ocean wave energy, developing energy converters (WECs) requires model test experiments, but there is limited knowledge on the consistency of results if an experiment reproduced in multiple basin laboratories. To better understand reproducibility WEC particular laboratory effects, we a 1:30 scale case study two This paper compares between laboratories evaluates whether, or degree to which, each experimental parameter contributed effects. Performance assessment tests were conducted intermediate-shallow water regular waves bottom-fixed oscillating-water-column (OWC) with nonlinear, unidirectional flow power take-off (PTO). Despite conducting experiments according international guidelines, found significant differences (15–30%) incident capture width ratio, due parameters associated environment (wave generation calibration, ambient conditions air) (deployment position, PTO modelling). Wave-WEC nonlinear interactions likely amplified interlaboratory differences. conclusion, effects can be and, therefore, should accounted for especially when are nonlinearities. We close recommendations address relevant WECs.
