After successful completion of the course, students are able to simulate the flow behaviour in turbomachinery and make suitable choices for required model settings. The successful student will be capable to judge the quality of the mesh and the credibility of the numerically obtained solution. Modelling techniques particular to turbomachinery flows will be familiar to the successful student.
During the course, we will apply numerical fluid mechanics to investigate the flow in turbomachinery applications. Turbomachinery, such as wind, gas, steam, Kaplan, Francis, or Pelton turbines, require many particular flow modelling techniques, which will be presented in this course. We cover all steps required to set up a successful simulation,
- pre-processing: geometry preparation, meshing, ...
- computation: choice of discretisation schemes, turbulence models, setting parameters, cluster calculations, ...
- post-processing: evaluation of quantities, plotting of results, ...
We will cover three examples, an airfoil, a U-turn pipe, and a turbomachinery component. The turbomachinery component is either a compressor or pump. The compuational results will be compared with experimental data for all three examples. The turbomachinery component can be measured optionally in the LU 302.694 - Thermal Turbomachines or LU 302.681 - Hydraulic Machinery and Hydraulic Systems I, respectively (this is not a requirement).
