   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser doppler velocimetry; vortex flow meter model; synthetic inlet boundary condition; circular cylinder in cross-flow; large-eddy simulations;

   Sammanfattning : The usage of Large-Eddy Simulations (LES) in industrial applications makes it possibleto study transient phenomena. The aim of this work is to find a reliable and accurateapproach to transient studies of the internal flow field in a vortex flow meter. LÄS MER

4. 3. A study of heat transfer from cylinders in turbulent flows by using thermochromic liquid crystals

   Författare :Roland Wiberg; KTH; []
   Nyckelord :Fluid mechanics; convection heat transfer;

   Sammanfattning : In gas quenching, metal parts are rapidly cooled from hightemperatures, and the convection heat transfer coefficientdistributions are of importance for the hardness and thedistortion (the shape nonuniformities) of the quenched parts.Thermochromic liquid crystals (TLC) and a thin foil techniques,were investi- gated and used for studies of a circular cylinderin axial flows, affected and not affected by upstream owmodifying inserts.
