Attività:

 

The objective is to carry out arc and thermal-fluid-dynamic simulations to evaluate the performance of a Generator Circuit Breaker (GCB) during operation under steady state and transient electrical loads.
The scope of the internship will be focused on the thermo-fluid dynamic and arc simulations. The candidate will receive dedicated assistance and support from the ABB engineers and scientists concerning the electrical component and arcs. Based on the results assist ABB engineers in the optimization of the device and in the validation and setup of a simplified model. Optional is the planning/design of validation experimental tests in collaboration with the ABB High Voltage Technology Center Team and ABB Corporate Research Center.

Your responsibilities:

  • Literature search on recent work regarding GCBs;
  • Implementation of the GCB CAD model in the dedicated thermo-fluid dynamic software;
  • Meshing of the GCB model;
  • Arc simulations and prediction of thermo-fluid-dynamic performances of a GCB by means of the software FLUENT
  • Data post-processing, analysis and evaluation of the results;
  • Propose improvements to the simulated case in collaboration with the ABB team;
  • Plan a dedicated validation campaign
Requisiti principali:
  • Bachelor or Master (preferred) in Mechanical Engineering, or a related field
  • Background in fluid-dynamics and thermal management
  • CAD knowledge (Creo is a plus)
  • CFD background (ANSYS FLUENT is a plus)
  • Meshing knowledge (ICEM, GAMBIT)
  • Proficiency in programming (Python)
  • Fluency in written and spoken English, German is a plus
  • Ability to work in a team, as well as willingness to handle responsibilities independently
