Abstract
An experimental investigation is carried out to study the
effect of several turn treatments like single guide vane (short
and long) and multiple guide vanes on the pressure drop distribution
in a square cross-sectioned smooth channel with a
sharp 180° bend. The sharp 180° turn is obtained by dividing
a rectangular passage into two square channels using a
divider wall with a rounded tip at the location where the
flow negotiates the turn. The study is carried out for a divider
wall thickness to hydraulic diameter
