A review on the progress and research directions of ocean engineering
TL;DR: In this article , the authors present a review of ocean engineering research over the last 50+ years with the aim to understand the technological challenges and evolution in the field, investigate whether ocean engineering studies meet present global demands, explore new scientific/engineering tools that may suggest pragmatic solutions to problems, and identify research and management gaps, and the way forward.

An investigation on the speed dependence of ice resistance using an advanced CFD+DEM approach based on pre-sawn ice tests
TL;DR: In this paper , the authors have built a computational model that can realistically simulate a ship advancing in a pre-sawn ice channel, which can decompose ship-ice interactions and investigate the speed-dependent resistance from broken ice pieces.

COVID-19 transmission inside a small passenger vessel: Risks and mitigation
TL;DR: In this paper , the authors developed a computational model to study the airborne transmission of COVID-19 viruses in the superstructure of a full-scale passenger vessel and found that keeping the forward door closed will help prevent the external wind flow spreading the virus.
Journal ArticleDOI
Towards a full-scale CFD guideline for simulating a ship advancing in open water
TL;DR: In this article , the authors explore an optimal approach for full-scale ship simulations and investigate their influence on the prediction of ship resistance, ship-generated waves as well as the boundary-layer flow of the hull.

General circulation experiments with the primitive equations
TL;DR: In this article, an extended period numerical integration of a baroclinic primitive equation model has been made for the simulation and the study of the dynamics of the atmosphere's general circulation, and the solution corresponding to external gravitational propagation is filtered by requiring the vertically integrated divergence to vanish identically.

A new version of detached-eddy simulation, resistant to ambiguous grid densities
Philippe R. Spalart,Sébastien Deck,Michael Shur,Kyle D. Squires,M. Kh. Strelets,Andrey Travin +5 more
TL;DR: In this paper, the authors proposed the DES97 model, denoted DES97 from here on, which can exhibit an incorrect behavior in thin boundary layers and shallow separation regions, when the grid spacing parallel to the wall becomes less than the boundary-layer thickness.

A hybrid RANS-LES approach with delayed-DES and wall-modelled LES capabilities
TL;DR: In this article, a CFD strategy is proposed that combines delayed detached-eddy simulation (DDES) with an improved RANS-LES hybrid model aimed at wall modelling in LES (WMLES).
