Originální abstrakt

The present work addresses a problem of the prediction of wall heat fluxes from swirling non-premixed staged gas flames in a large-scale furnace. The computational part unfolds from a central problem of predicting the swirling flow generated by guide vane swirler. Due to the non-symmetry of the flow in the swirler and bad access for detailed measurement in the burner inlet, it was decided to include the air supply duct in the simulation. However, it is well known that prediction of the action of swirl generator is extremely difficult and thus a validation of the code is carried out using published measurements in a similar, but laboratory-scale, device.
