Rearch Program: Wind Assisted Ship Propulsion

The maritime industry is under pressure to reach the net-zero Greenhouse Gas target set for 2050 on international shipping to alleviate the climate crisis. A strong collaboration between industry, research institutes, and universities is needed to develop and implement novel technologies to achieve this target.

In response to this challenge, TU Delft recently launched a multi-disciplinary, interfaculty research program on Wind Assisted Ship Propulsion (WASP) focusing on three research themes: 1) Fluid dynamics, 2) Design and operation, and 3) Sustainable and societal impact. We are a young, international and diverse team within the Faculties of Aerospace and Mechanical Engineering. We approach problems in a horizontal “team spirit” and continuously traverse boundaries between theory, simulations, and experiments. We strive for a co-creative and stimulating environment where you can develop further skills as a scientist, team member and teacher. We place great emphasis on a collegial working environment where everyone is welcome and encouraged to shape a stimulating and impactful PhD track. In addition, given the multi-disciplinary nature of wind-assisted technologies, your research will contribute to other projects on different themes within the WASP program.

PhD Position: Benchmark towing tank tests for wind assisted ships and performance assessment of auxiliary appendages

To predict the performance and the forces acting on wind assisted vessels Computational Fluid Dynamics (CFD) tools are increasingly applied. However, experimental validation remains crucial for refining these predictions, particularly in complex hydrodynamic scenarios. This PhD position focuses on using towing tank tests and high fidelity flow field measurements using Particle Image Velocimetry (PIV) to enhance our understanding of wind-assisted ships and the performance of auxiliary appendages under various conditions.

The goal of this research is to conduct detailed model-scale tests to support the development of high-fidelity CFD tools, especially for ships operating at drift angles with additional appendages. This includes both validation of CFD codes and assessment of the impact of various appendage configurations on flow dynamics and performance.

The primary tasks of the PhD involve:

1. PIV System Optimization: Review and optimize the PIV system components to accurately measure flow fields close to the hull and appendages of a ship at drift angles.

2. High-Fidelity Validation: Conduct detailed flow field and force measurements on a bare hull at varying drift angles to validate CFD simulations.

3. Performance Assessment of Appendages: Experimentally assess the performance of various appendages and their influence on the flow field at model scale.

4. Full-Scale Extrapolation: Translate experimental findings on appendages to full-scale applications using numerical simulations with a calibrated RANS model.

Job requirements 

We welcome applicants with diverse backgrounds to enrich our dynamic and diverse research group, especially individuals with a background in Mechanical and Maritime Engineering, or Applied Physics. Assertive students with a strong academic standing are encouraged to apply. Strong interest in fluid dynamics and previous experience with experimental or laboratory work are appreciated. Previous experience in computational fluid dynamics and programming is highly valued in the selection.

Faculty Mechanical Engineering

From chip to ship. From machine to human being. From idea to solution. Driven by a deep-rooted desire to understand our environment and discover its underlying mechanisms, research and education at the ME faculty focusses on fundamental understanding, design, production including application and product improvement, materials, processes and (mechanical) systems.

ME is a dynamic and innovative faculty with high-tech lab facilities and international reach. It’s a large faculty but also versatile, so we can often make unique connections by combining different disciplines. This is reflected in ME’s outstanding, state-of-the-art education, which trains students to become responsible and socially engaged engineers and scientists. We translate our knowledge and insights into solutions to societal issues, contributing to a sustainable society and to the development of prosperity and well-being. That is what unites us in pioneering research, inspiring education and (inter)national cooperation.
