Abstract: Heat transfer characteristics in rectangular with a
sharp 180o turn
have been examined experimentally using the naphthalene
sublimation method. The sharp 180° turn was obtained by dividing a rectangular
passage into two channels using a divider wall with a rounded tip at the location
where the flow negotiates the turn. The channel cross-section (WxH) is 50×25 m,
and three turn clearances of 30, 50, and 70 mm have been tested in this study.
Local mass transfer rates on all walls of the channel have been measured to
clarify the heat transfer characteristics in the channel. The result indicated
that the highest coefficient of heat transfer was achieved in the channel with
turn clearances of 30 mm.
