Název v původním jazyce

Numerical Flow Simulation in an Unconventional Wheel Chamber

Popis výsledku v původním jazyce

The report focuses on numerical flow simulation for an untraditionally interpreted steam turbine wheel chamber, i.e. inside the flow duct, which transfers the flow between the turbine degree with partial admission into the following degree with full admission. Previous research demonstrated that the standard wheel chamber with a simple concept of structure is not capable of entirely eliminating the effect partial admission has on the distribution uniformity of flow parameters on the inlet of the following degree with full admission, which is adversely demonstrated on the turbine efficiency. The fundamental idea to make modifications was firstly verified during an experiment by easily modifying the shape of the standard duct walls and subsequently an entirely new flow duct shape was designed and verified in the CFD program. The results confirm that the newly arranged duct practically eliminates the distribution uniformity of flow parameters
