MASTER THESES | “EuroValve” PROJECT

CFD simulation of a safety valve and investigation of the forces acting on the safety valve disc.

Construction of a two-dimensional simulation of a safety valve and investigation of the forces acting on the safety valve disc. It is possible to build on previous simulations and measurements.

Working steps:

• Literature research on available simulations and measurements
• Definition of relevant influential parameters on the distribution of the flow force at the valve disc
• Creation of a two-dimensional simulation of the flow forces
  at the valve disc based on an existing safety valve for single-phase compressible media
• Sensitivity analysis in relation to the relevant influential parameters

MASTER THESES | PROJECT “sRMC”

Development of a physical model for gas leaks to validate the sensor data of an intelligent early detection system

Within the scope of this work, a physical model for gas leakages is to be developed for the validation of previously defined sensor systems of an early detection system.

Working steps:

• Literature research to determine the characteristics of non-permissible leakage
• Definition of the requirements for an early detection system with multi-sensor technology for the detection of gas leaks
• Systematic selection of suitable sensors for measuring sound (frequency/volume), vibration, temperature and medium
• Development of a physical model of a leakage flow and determination of a gas leakage mass flow on the basis of the previously
  defined measured quantities.
• Planning of an experimental set-up to test the sensors and the model in the laboratory for weak points, accuracies and detection bands.
