Flow through an interrupted or enhanced heat exchanger passage is complicated and may
cause the natural formation f vortices that can enhance local heat transfer by several …

The prediction of turbulent flows is a nontrivial problem in internal and external
aerodynamics and in many other branches of engineering. The problem appears in perhaps …

Transition between nucleate and film boiling potentially causes dramatic temperature
changes during fluxcontrolled operations, which may lead to catastrophic equipment …

Longitudinal vortices are more efficient for heat transfer enhancement than transverse
vortices. A survey is given on triangular and rectangular protrusions from a heat transfer …

Triangular and rectangular longitudinal vortex generators were formed by punching small
pieces out of flat plate fins so that they stuck out of the plates and formed an angle (angle of …

This study presents numerical computation results on laminar convection heat transfer in a
rectangular channel with a pair of rectangular winglets longitudinal vortex generator …

Longitudinal vortices have enormous utility for flow control. Longitudinal vortices are also
capable of producing beneficial effects in transport enhancement. The vortices disrupt the …

LONGITUDINAL vortices embedded in turbulent bound-ary layers occur naturally in many
flows and are purposely induced in other flows. Naturally occurring vortices are often found …

Numerical and experimental analyses were carried out to study the heat transfer and flow in
the plate-fin and tube heat exchangers with inclined block shape vortex generators mounted …

This study experimentally investigates the heat transfer and friction factor (f) characteristics
of a tube fitted with cross hollow twisted tape inserts of hollow widths of 6, 8 and 10 mm …
