PREDICTING THE RESPONSE OF SMALL-SCALE NEAR-WALL TURBULENCE TO LARGE-SCALE OUTER MOTIONS etc15 Tracking Number 299Presentation: Session: Wall-bounded flows 1 Room: Room M Session start: 10:30 Tue 25 Aug 2015 Lionel Dr. Agostini agostinilionel@gmail.com Affifliation: Ohio State University Michael Prof. Leschziner mike.leschziner@ic.ac.uk Affifliation: Imperial College London Topics: - Wall bounded flows Abstract: Abstract: The paper deals with the question of how to determine – or “predict” - the near-wall-turbulence statistics from a Reynolds-number-independent, “universal”, small-scale signal, and the Reynolds-number-dependent large-scale outer motions in the log layer. An empirical model is proposed, which is intended to take into account the effect of “splatting”, not previously considered, thus offering an improved representation of the near-wall-turbulence field. |
