On behalf of the Steering Committee, we can inform you that the date for the Wageningen 2025 Workshop on CFD in Ship Hydrodynamics has been set! The workshop will be held from Monday November 17^th to Wednesday November 19^th at Hotel De Wageningsche Berg, in Wageningen, The Netherlands.

Four of the test cases have been fully defined and we are working hard to finalize the last test case on turbulence. The aim of the JBC Turbulence Test Case will be on physical understanding of the mean and unsteady turbulence structure and 3D vortex separation for ship flows. Particular focus will be placed on anisotropic RANS and scale resolving simulation methods and their simulation of the flow in the propeller and rudder regions. The test case will use the conditions of the T2015 JBC 1.1a and 1.3a test cases (see https://www.t2015.nmri.go.jp/) with expanded analysis, including steady and unsteady primary and secondary vortex core analysis of the turbulence realizability and anisotropy and Taylor macro and micro scales and Kolmogorov spectrums. All the available experimental data will also be assessed and used for validation along with model spectrums based on the macro scales for both the experiments and simulations. Test case 1.3a will be for fixed sinkage and trim at the experimental values and for codes that do not have free surface capability double body simulations at zero sinkage and trim will also be accepted.

We look forward to your participation in W2025. Please bring this announcement to the attention of any other prospective persons who would be interested in participating in the Workshop. Visit our website https://w2025.nl for the latest news.
