Project/Bachelor's/Master's project and master's theses in the Schultz working group

In-house theses represent a special quality feature, since the students are given both strictly application and industry-related experience as well as engineering laboratory tasks.

In-house theses (project/bachelor's/master's project and master's theses) on current research topics can be prepared in the Schultz group at any time. Since the number of laboratory places is limited and they are in great demand, an early inquiry/application is recommended.

Suitable candidates are guaranteed optimal supervision and have the opportunity to work on modern equipment (pressure reactors, stirring apparatus, columns, etc.) as well as to use innovative measurement systems (Particle Image Velocimetry (PIV), Laser Induced Fluorescense (LIF), high-speed cameras, shadowgraphy, etc.).

Furthermore, there is the possibility to use the infrastructure of the ILOC.

The topics are on current research areas and furthermore often in cooperation with industrial companies.

Specialisation/questions:

• Questions in the field of mass and heat transport as well as chemical engineering
• Stirring and mixing technology
• Fluid and particle flow
• Size reduction technology
• Computational Fluid Dynamics (CFD)
• Gas hydrates:
  • Flow insurance, prevention of gas hydrate formation in pipelines
  • Gas separation by gas hydrate formation,
  • Gas storage in the form of gas hydrates,
  • gas transport in the form of gas hydrates,
  • _{CO2 deposition} in the form of gas hydrates,
  • energy production from gas hydrates
  • (Waste) water treatment and seawater desalination by gas hydrate formation

Current topics offered:

Attention: Depending on the number of theses currently in progress, the limitation due to the number of available workstations has to be considered. This can lead to delay or even rejection of a topic in case of high demand and has to be clarified in a personal conversation considering the desired time period.

Currently various topics on offer.

If you are interested and/or have questions, please contact Prof. Schultz, room S E19.

You bring with you:

• Advanced studies with specialisation in Technical Chemistry
• Good MS-Office skills
• An independent, responsible way of working
