PhD: Continuum Two-Phase Flow for Safer Dike Design

Delft; Delft; On-site; EUR 34,000 - 42,000; Full time

Job summary

TU Delft invites applications for a PhD position focused on continuum two-phase flow modelling of piping in dikes. You will combine fundamental fluid–soil interaction physics with computational modelling to advance safety of flood defences.

You will develop models, derive constitutive relations from DNS-DEM data, and address multi-scale challenges while keeping computations efficient. The role includes publishing results and presenting at conferences.

Qualifications

• MSc in a relevant engineering or science field.
• Training in multiphase flow physics, numerical methods, and CFD.
• Excellent English communication and collaboration skills.
• Affinity with teaching MSc students.
• Familiarity with Euler–Euler modelling and mesh adaptation is a plus.

Responsibilities

• Develop continuum-based two-phase models to predict internal erosion and pipe progression in clay-sand layered dikes.
• Derive constitutive modelling approaches from high-fidelity DNS-DEM data within the project consortium.
• Capture multi-scale pipe formation while maintaining computational efficiency; explore adaptive mesh refinement.
• Disseminate results via publications, conferences, and interdisciplinary collaboration.
