Research Associate (m/f/x)

Advanced experimental and numerical study of bubble dynamics in the injection zone of pool scrubbing

(subject to personal qualification, employees are remunerated according to salary group E 13 TV-L)

starting October 1, 2026. The position is limited until June 30, 2029 and entails 75 % of the fulltime weekly hours. The period of employment is governed by the Fixed Term Research Contracts Act (Wissenschaftszeitvertragsgesetz-WissZeitVG). The position offers the chance to obtain further academic qualification (usually PhD).

Tasks: Investigation of bubble size evolution in the injection and transition zone of pool scrubbing. The following tasks are to be carried out in detail:

• design and setup of an experimental facility for investigating gas injection and globule/bubble size evolution using ultrafast X-ray computed tomography (ROFEX)
• systematic experimental study and comparative evaluation of different gas flow rates and nozzle geometries
• development and application of morphology-adaptive two-fluid simulations using OpenFOAM
• provision of bubble size distributions in the swarm flow regime for project partners
• investigation of the influence of the injection zone on overall scrubbing efficiency

Requirements:

• excellent university degree (Diploma or Master’s) in Mechanical Engineering, Chemical and Process Engineering, Nuclear Engineering, Computational Science, or a related field
• strong interdisciplinary mindset, combined with practical experimental and numerical skills; ability to actively communicate and collaborate with project partners and team members are essential for successful project execution
• very good fundamental knowledge of mathematics and physics is desirable
• ability to quickly familiarize yourself with new topics, combined with a results-oriented, independent, and team-oriented working style
• proficiency in English for scientific communication (written and spoken)
