EFFECT OF VERTICAL PARTITION
PLATE ON THERMAL FLUID-FLOW IN OPEN RECTANGULAR CAVITY WITH INJECTION AND
SUCTION DUCTS
Shuichi Torii (Japan)

Abstract: An experimental study is performed on convection heat
transfer and fluid flow in an insulated open rectangular cavity, i.e., an open
indoor room with the injection and suction ducts. Emphasis is placed on the
effect of vertical partition plate in the open cavity on the thermal and
velocity fields and local area heating-performance. The numerical method is
based on the incompressible Navier-Stokes and energy equations. The fluid in the
closed cavity in the absence of the vertical partition plate shows the large
clockwise flow pattern. In contrast, when the vertical wall is opened, the hot
fluid flows through the opened area, resulting in a substantial attenuation of
the room temperature over the whole region of the cavity. When the vertical
plate is installed at the central location of the upper horizontal wall, the
higher velocity field appears in the left area of the cavity and the
corresponding fluid temperature is higher than that of the right area. The same
trend was maintained in the left area of the cavity although the vertical wall
in the cavity was
opened. By installing the
partition plate, the
temperature distribution in the indoor is controlled. In other words,
only the desired space of the cavity is warmed, because the flow pattern is
changed due to the presence of the plate. |
