Abstract:Trawl nets are mostly flexible structures working in the water. In order to investigate the effect of the fluid-structure interaction on the trawl net's numerical model, we modeled the trawl net and the flow field based on lumped mass method and finite volume method, separately; then we adopted a hybrid volume method (HVM) to model the fluid-structure interaction between the net and surrounding water. Since the gridding of trawl net is independent of its shape within the proposed HVM, large mesh can be used fo… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
