ABSTRACT

Convection heat transfer measurements were performed in an air flowing over an open rectangular cavity. The open rectangular cavity was installed at the lower part of a horizontal rectangular wind channel, and an one row arrangement of spherical particles was provided in the cavity. Air flowing through the channel was heated via the particle layer from the bottom heating surface of the cavity. The heat transfer results were correlated by using the parameters which represented the effects of the air velocity, particle thermal conductivity, cavity depth and temperature difference between the incoming air and the heating surface.
