A fully funded PhD position is available at the Department of Marine Environment and Engineering, National Sun Yat-sen University (Kaohsiung, Taiwan). The research will examine the coupled dynamics of wind, surface waves, and ocean currents that set the structure of the marine boundary layers. In energetic conditions, wave breaking, spray formation, and bubble entrainment introduce additional multiphase pathways for momentum and energy exchange across the air–sea interface, yet these effects remain poorly represented in existing models. The project will develop turbulence closures that capture both the baseline wind–wave–current coupling and its multiphase feedbacks, advancing Large-Eddy Simulation (LES) of marine boundary layers and enabling improved assessment of offshore wind resources.
Your Role
This PhD project combines physical analysis with turbulence model development. Your primary role will be to:
Analyze two-phase Direct Numerical Simulation (DNS) datasets to identify the mechanisms governing air–sea exchange in marine boundary layers
Design and implement new subgrid-scale (SGS) closures for LES, using both physics-based formulations and machine learning approaches
Investigate wind–wave–current coupling at scales relevant for offshore wind applications
Candidate Profile
Master’s degree in Mechanical, Civil, or Ocean Engineering, Physics, Applied Mathematics, or a closely related field
Interest in fluid mechanics and turbulence, with willingness to learn modeling approaches
Motivation to apply advanced numerical methods to ocean and wind energy problems
Programming experience (C++ and/or Python), with CFD experience as an asset
Proficiency in academic English
Offer
Fully funded PhD position with tuition waiver and monthly stipend
Access to Taiwan’s national supercomputing resources
Support in applying for competitive external fellowships
