The Bundesanstalt für Materialforschung und -prüfung (BAM) is a senior scientific and technical federal institute with responsibility to the Federal Ministry for Economic Affairs and Climate Action. It tests, researches, and advises to protect people, the environment and material goods.
The Safety of Transport Containers division is engaged with research, testing and assessment of transport containers for radioactive materials. This includes mechanical and thermal safety verifications and the development of experimental and computational test methods for the analysis of transport containers.
As part of the experimental work, we perform a variety of load tests at our BAM Test Site for Technical Safety (BAM-TTS) close to Berlin. We offer good and close supervision of the work in a scientific environment.
Topic of the Thesis
At the BAM Federal Institute for Materials Research and Testing, the division "Safety of Transport Containers" deals, among other things, with the topic of heat input and heat dissipation in containers for dangerous goods. A specific academic study aims to analyze the distinctive properties of a propane gas flame using Ansys® Fluent or OpenFOAM software. The study involves incorporating multiple burner nozzles and examining their interaction with a test object within a model. Various parameters, including distance, angle, and mass flow rate, are to be analyzed and compared to achieve the optimal flame configuration around the test object. To facilitate this analysis, a generic model with customizable parameters must be developed. While the external boundary conditions, such as stagnant ambient air, remain fixed, the study focuses on investigating flame characteristics like mass flow rate and velocity through parameter studies. The goal of the research is to explore the surrounding fire pattern around the test object based on the aforementioned parameters.
Task of the Thesis
This project entails the development and parameterization of a model for a generic fire testing apparatus, incorporating appropriate boundary conditions. The Computational Fluid Dynamics (CFD) analysis will be performed using either Ansys® Fluent or OpenFOAM software. Key parameters will be identified and analysed through an examination of an existing fire testing apparatus with a similar design. A literature search will be conducted to identify suitable modelling approaches and relevant boundary conditions that align with the specific requirements of the study. Fluid characteristics such as velocity, pressure, laminar flow, turbulent flow, and combustion will be scrutinized and categorized as part of the numerical investigations.
