ABSTRACT

This paper outlines the design and development of a rainfall simulator for the centrifuge for the purpose of evaluating infrastructure resilience in changing climate conditions. Pressure losses in the water supply system are evaluated and related to nozzle pressure and flow rate at both 1 g and elevated gravity up to 100 g. Coriolis effects are investigated and quantified with increasing gravity accounting for effects of air flow through the experimental package on the University of Sheffield 50 gT beam centrifuge. The rainfall simulation capabilities are demonstrated on a slope boundary problem to validate the developed system. Slope deformation is captured using digital image correlation techniques which confirm triggering of slope movements with applied rainfall events.
