Abstract

This paper presents a novel method to ensure that designs generated by topology optimization have the property that fluids can be drained from them. This is a crucial aspect in design for cleanability, which is important in e.g. food, health, space and high-tech industries. To ensure cleanliness, stagnant fluids remaining from cleaning operations are to be avoided rigorously. Inspired by geometric constraints developed for overhang angle control in additive manufacturing, a filter procedure is proposed that ensures that generated designs fulfil the drainability requirement. Its effectiveness is demonstrated by several numerical examples, including an industrial design case.
