As outlined in the Tokyo CFD Workshop 2015, reliably reproducing the turbulent kinetic energy and vorticity in the wake of the Japan Bulk Carrier (JBC) hull is still a challenge to contemporary CFD methods (Hino, et al., 2021). Depending on the applied turbulence modeling approach, a wide variance of fluid characteristics can be observed. In numerical simulations, the accuracy of resolving the stationary vortices induced along the ship hull and quantifying their strength is part of current research investigations (see Visonneau, et al., 2016, Shevchuk, et al., 2016). This topic is especially important for the static drift condition, under which the vortical structures can have a significant influence on the interaction between the hull and propeller and lead to high fluctuations of propeller and hull drift forces. The objective of this study is the numerical investigation of the hull-propeller interaction of the JBC hull under static drift condition. Taking the propeller into account leads to two different scenarios that are investigated: positive and negative drift. This results in two operational conditions of the propeller. Within the numerical study a RANS approach as well as DES methods are applied in order to investigate the influence of the applied turbulence model on the flow structure. The numerical model is validated based on extensive results from the Tomographic Particle Image Velocimetry measurements with and without propeller, which are presented and compared to the CFD results. A detailed analysis of hull and propeller forces will be presented in this paper.
