Description
  • Okamžité hodnoty smykové rychlosti na stěně byly měřeny v tokovém kanále za náhlým rozšířením. Dvojpáskové elektrodifuzní čidlo bylo využito pro získání informací o směru proudění v těsné blízkosti stěny. Pro hodnoty Reynoldsova čísla od 30 do 1800 byly měřeny podélné profily smykové rychlosti při stěně a určeny polohy bodu opětovného přilnutí odtržené mezní vrstvy. Získané experimentální výsledky jsou v dobré shodě s dříve publikovanými numerickými daty. (cs)
  • A backward-facing step flow is studied by measuring the instantaneous wall shear rate along the channel certenline. A two-step electrodiffusion probe is applied to provide information on the flow direction in the near-wall region. The wall shear rate profiles behind the step are measured and the position of reattachment point detected. The Reynolds numbers examined cover the laminar, transient and beginning of turbulent flow regime. The results are found to be in a good agreement with the experimental and numerical data previously published for the same channel geometry.
