Proudění uvnitř idealizované městské zástavbě
Bezpalcová, Klára ; Harms, F. ; Leitl, B. ; Jaňour, Zbyněk
The regular obstacle array of the Mock Urban Setting Test (MUST) fiedl site in the Utah West Desert (USA) has been replicated in the large boundary layer wind tunnel at University of Hamburg. The trials run during the field campaign were repeated in the wind tunnel as well as additional measurements of flow.The strong flow inhomogeneities were observed on the vertical profiles of shear stress as well as on the horizontal mean flow for different array orientation.

Výzkum turbulance pomocí metod pro analýzu dynamických systémů
Uruba, Václav
Turbulence represent itself very important and common behaviour of real fluids. It is usually treated using special methods based on probabilistic approach. In the presented study methods originally developed for chaotic dynamical systems are applied to turbulent fluids. Problem of the continuous system discretization to develop phase space is analyzed in details.
