As a subsidiary of the Swedish Saab Group, we employ around 130 people in Switzerland. We develop, produce and sell technologically sophisticated goods for the defense industry and the civil sector. Join our team and explore the fascinating world of explosives technology!

We're seeking a highly motivated student for a

6-month internship or Master's thesis project

Understanding the solidification dynamics of melt-cast explosives, such as TNT (trinitrotoluene), is crucial for optimizing their manufacturing process and ensuring consistent quality and safety. This master’s thesis or internship proposes a numerical and experimental investigation of the solidification behavior of TNT, focusing on the key factors influencing the solidification process.

Objectives and Methodology

• Numerical Modeling:

  Develop a numerical model to simulate the solidification process of TNT, focusing on heat transfer and phase change under controlled cooling rates.
  • Review existing literature on the solidification of explosives and heat transfer phenomena.
  • Develop a mathematical model incorporating heat transfer and latent heat release during TNT solidification, considering its thermal properties.
  • Implement the model using a numerical solver (e.g., Python with NumPy) to simulate the solidification process under different cooling rates.

• Experimental Validation:

  Conduct experiments to measure the solidification kinetics of TNT under controlled cooling rates and validate the numerical predictions.
  • Design and implement an experimental setup for melt-casting TNT under controlled cooling conditions.
  • Utilize thermocouples to measure the temperature evolution during solidification at various locations within the TNT sample.
  • Compare experimental temperature profiles with numerical predictions to validate the model.

Qualifications & Requirements

• BS in physics, chemistry, material science or similar
• Previous experience and solid understanding of numerical methods and modelling techniques, programming and data analysis
• Ability to design experimental setups including temperature measurement and data acquisition
