Influence of approach flow conditions on heat transfer behind vortex generators

A method to visualise near wall fluid flow patterns using locally resolved heat transfer experiments

“…The other two heat transfer enhancement branches, originated by the secondary vortices, vanish at approximately x/L = 1 and no further traces of enhanced heat transfer can be seen. Note that all these observations are consistent with Henze et al [8] and Henze and von Wolfersdorf [16]. Finally, it should be noted that from the trailing edge of the VG, the heat transfer coefficients are gradually reduced.…”

Enhancing heat transfer in a plate-fin heat sink using delta winglet vortex generators

“…Henze et al [12,13] studied the transfer of heat in internal flows with the presence of longitudinal vortices that were induced by tetrahedral vortex generators. Their results revealed that the highest vortex generator provided the highest heat transfer enhancement, and that increasing the Reynolds number increased the heat transfer coefficients.…”

“…Henze and Wolfersdorf [3] investigated the influences of tetrahedral VG in the heat transfer test section. They claimed that the highest VG height provides the highest heat transfer enhancement.…”
