The Department of Computational Fluid Dynamics is looking for a PhD Student (f / m / d) Euler-Euler Modelling of Gas-Liquid Flow with Phase Change , subject to final approval by the project sponsor.

Your tasks

• Identifying the influence of phase change on bubble dynamics and hydrodynamics, particularly coalescence and breakup
• Evaluating state-of-the-art Euler-Euler models for gas-liquid flows with phase change (condensation and evaporation)
• Developing and improving bubble coalescence and breakup models to incorporate phase-change effects
• Investigating bubble nucleation and growth under depressurization conditions
• Simulating phase-change phenomena within the riser of a natural circulation loop
• Collaborating with project partners on experimental design, data analysis, and simulation setup

Your profile

• Completed university studies (Master / Diploma) in the field of Mechanical Engineering, Chemical Engineering, Computational Science, Physics or related field
• Solid understanding of fluid mechanics, multiphase flows, and numerical methods
• Solid knowledge on computational fluid dynamics (CFD)
• Strong communication skills and enthusiasm for working in an interdisciplinary environment
• Excellent written and spoken English skills
• Practical experience with computational fluid dynamics (CFD) and programming

Our offer

• A vibrant research community in an open, diverse and international work environment
• Scientific excellence and extensive professional networking opportunities
• A structured PhD program with a comprehensive range of continuing education and networking opportunities - more information about the PhD program at the HZDR can be found
• Salary and social benefits in accordance with the collective agreement for the public sector (TVöD-Bund) including 30 days of paid holiday leave, company pension scheme (VBL)
• We support a good work-life balance with the possibility of part-time employment, mobile working and flexible working hours
• Numerous company health management offerings
• Employee discounts with well-known providers via the platform Corporate Benefits
• An employer subsidy for the "Deutschland-Ticket Jobticket"

We look forward to receiving your application documents (including cover letter, CV, diplomas / transcripts, etc.), which you can submit via our online-application-system.
