A Modified Moving Reference Frame Method for Propeller Resolution
Denis Andreev, Georgios Bletsos, Antonios Kritikos +2
Accurate resolution of propeller-hull interaction is essential for predicting the self-propulsion point in ship CFD, yet motion-resolving methods such as sliding interfaces (SI) ar…
Rapid Aerodynamic Assessment of Flettner Rotor Installations Using an Inviscid CFD Approach
Niklas Kühl
This paper introduces an inviscid Computational Fluid Dynamics (CFD) approach for the rapid aerodynamic assessment of Flettner rotor systems on ships. The method relies on the Eule…
Identification of Beneficial and Detrimental Structure Locations Around Flettner Rotors Using Topology-Optimization-Inspired Sensitivity Fields
Niklas Kühl
Flettner rotors are highly sensitive to their surrounding flow field and may be significantly affected by nearby ship structures, deck cargo, and superstructures. Assessing the aer…
Incremental Singular Value Decomposition Based Model Order Reduction of Scale Resolving Fluid Dynamic Simulations
Niklas Kühl
Scale-resolving flow simulations often feature several million [thousand] spatial [temporal] discrete degrees of freedom. When storing or re-using these data, e.g., to subsequently…
Two-Phase Flow Simulations of Surface Waves in Wind-Forced Conditions
Malte Loft, Niklas Kühl, Marc P. Buckley +4
The paper is devoted to two-phase flow simulations and investigates the ability of a diffusive interface Cahn-Hilliard Volume-of-Fluid model to capture the dynamics of the air-sea…
Adjoint Complement to the Volume-of-Fluid Method for Immiscible Flows
Niklas Kühl, Jörn Kröger, Martin Siebenborn +2
The paper is concerned with an adjoint complement to the Volume-of-Fluid (VoF) method for immiscible two-phase flows, e.g. air and water, which is widely used in marine engineering…
