  3. 2. 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.
