Original abstract

There is industrial demand to investigate reasons for creation of swirl at a pump inlet. Victor Kaplans Department of Fluid Engineering was asked to investigate flow in the test well and effect of the test well configuration and the discharge pipe diameter on velocity field and pre-swirl intensity at pump inlet. The obtained results and our conclusions are summarized in this contribution. The main task was to confirm or disprove usability of the test well for testing vertical pumps of flow rates up to 10000 m3/h. The existing test well was commonly used for testing pumps of flow rates up to 4300 m3/h without any problems.

Obsahem příspěvku je CFD analýza proudění v sacím potrubí v závislosti na uspořádaní nádrže. Byla zkoumán vliv průměru vratného potrubí a dále vliv přítomnosti bočních výklenků nádrže.
