DOI: 10.1016/j.ijmultiphaseflow.2018.04.016
Abstract: Air cavities, i.e. air layers developed behind cavitators, are seen as a promising drag reducing method in the maritime industry. Here we utilize the Taylor-Couette (TC) geometry, i.e. the flow between two concentric, independently rotating… read more here.
